Pastor Ken Temple is a Reformed Protestant anti-Catholic polemicist, whom I have engaged numerous times. His words will be in blue.
I wrote, in the above dialogue:
Oftentimes, sadly, yes, because human beings have an endless capacity for self-deception, self-justification, and rationalization. What we need to remember regarding idolatry, is that it resides internally in the heart, first and foremost. One has to be consciously aware of what they are doing and what they believe. If a person is to replace God with a saint (as if the latter is equal to or higher than God), then they are consciously, deliberately doing so, or else it isn’t idolatry per se. It may be spiritual laxity or even gross negligence, but not idolatry.
Ken then asked:
Do you think the apostle John was consciously and deliberately committing idolatry when he bowed down to the angel and was rebuked for it in Revelation 19:10 and 22:8-9?
Revelation 19:10 Then I fell down at his feet to worship him, but he said to me, “You must not do that! I am a fellow servant with you and your brethren who hold the testimony of Jesus. Worship God.” For the testimony of Jesus is the spirit of prophecy.
Revelation 22:8-9 I John am he who heard and saw these things. And when I heard and saw them, I fell down to worship at the feet of the angel who showed them to me;  but he said to me, “You must not do that! I am a fellow servant with you and your brethren the prophets, and with those who keep the words of this book. Worship God.”
Fair question. Here’s what I think about that:
It is the spontaneous reaction of human beings (seen throughout Scripture) to be awed by angelic appearances or theophanies or direct manifestations of God.
In the moment you don’t think “this is just an angel.” You react with awe, which is what John did. He wasn’t thinking theologically, as we have the luxury to do in our armchairs, but he was thinking, “this is a far greater Being than I!”
Moreover (and more to the point at hand), often in the Old Testament the Lord and His Angel (“angel of the Lord”) are virtually indistinguishable, to the extent that these angels are called angels in one second and God in the next, so it wouldn’t necessarily be clear which was the case.
Even in the burning bush, there is a reference to “the Angel of the Lord” (Ex 3:2) and yet two verses later, “God called to him out of the bush.” John may have very well thought that this was a direct manifestation of God, in that sense, but was mistaken and corrected by the angel.
That’s what I think was primarily going on, in which case it wasn’t idolatry at all, because he thought it was God, or such a direct communication from God through the angel that “worship” was the proper response.
My take apparently isn’t an isolated one. The old [Catholic] Haydock Commentary stated at 19:10:
St. Athanasius and St. Augustine think St. John took the angel to be Jesus Christ, and as such was desirous of paying him the supreme homage, or latria.
Not bad company or support for an exegetical opinion, but Ken is quite capable of blowing them off, if they don’t support his (anti-Catholic) line of reasoning. Ken then counter-replied (the blue print below). My original answer was as follows:
We can speculate all day what we think an angel or God or inspired writer coulda woulda shoulda said. I think my answer was quite sufficient. As usual with you, we could go round and round forever, . . . You disagree, huh? Another shocking revelation! The anti-Catholic disagrees with the Catholic take! Stop the presses!
But since Ken is pushing the issue with a new provocative post, I decided to expand upon my reply.
I appreciate the way you answered that.
So, why did the angel rebuke John for it?
Because (I think) he had mistaken him for Jesus. It was a category / identification mistake.
Since you say he was temporarily overwhelmed and/ or thought it was a Theophany – like in Genesis 16, or Gen. 18 or Joshua 5, etc. in which case it would not have been truly idolatry (In your opinion), why did the angel rebuke him for it?
See my last reply.
Since it does seem like it was sometimes Theophanies in the OT – and John is an apostle ( !!!)
Seems like if that was going on in John’s mind, the angel should have said, “that’s ok, I realize you think I am “the angel of the Lord” as in Genesis 16 or 18 or the Captain of the Lord’s host in Joshua 5 (Theophanies), but I am not; I am just a creature created by God; but since you have subjectively distinguished in your mind and heart; then that is ok, since you are sincere. “
But the angel did not do that – he said “don’t do that!” and “Worship God!”
Yes, and he said, “I am a fellow servant with you” (19:10). I don’t see any implausibility in believing as I do, with regard to the angel’s response. It makes perfect sense in that scenario. He just didn’t say as much as you thought he should. Big wow.
John sincerely thought it was God, in your opinion, or was just emotionally overwhelmed with “this being is mightier than me”
But in Roman Catholic Marian Piety, there is deliberate and planned and structured prayers and with flowering language of praise and many times descriptions that should only be reserved for God – ” I fly to you for refuge”, “I cast my anxieties to you, O Mother of God”; “save me in this hour”, etc. So, there is no suddenly being overwhelmed in RC Marian Piety. And in RC Marian Piety, they are supposed to know in their mind that this statue of a woman is not God nor a manifestation of God; and indeed they probably DO realize that.
That’s another topic entirely, and I don’t play the rabbit trail” game. But, nice try.
And John realizes that also, once the angel tells him that he is not a theophany as in Genesis 18 or Joshua 5. So why does the angel say, don’t do that, and only worship God?
See my 4th reply up, above.
I think it is obvious that it gives the appearance of idolatry, and no one can tell the difference between real idolatry and RC Marian piety. Only the devotee him or herself can testify as to the subjective experience in their heart and mind.
Now I will flesh out my argument here a bit. As to the sometimes “textual confusion” of the “angel of the Lord” and God Himself, see, for example:
The text in-between goes back and forth, referring to “men” or “they” or “them” (18:9, 16) and “The LORD” or first-person address from God (18:10, 13-14, 17-21) interchangeably, for the same phenomenon and personal / physical / verbal encounter. But there are three men here; they can’t all plausibly be God. Two of them were angels (indicated by 18:22 and 19:1). Thus, Abraham venerated them, too. St. Augustine argued that all three men were angels, but this seems ruled out by the presence (twice) in the text, of “the LORD”.
A “man” is equated with God also in Genesis 32:24, 30. See the related passages Ex 3:2-6; Num 22:22-27, 31-35; Jud 6:12-16, 20-23. Here is a particularly striking and explicit example of this confusion:
This passage is remarkable in that it goes back and forth between God (13:16, 19, 22) and the angel of the Lord (or of God) as His direct representative (13:15-18, 20-21 and in the larger passage, 13:3, 6, 9, 13). The angel is honored (v. 17), they fall on their faces to worship (v. 20) and at length the angel is equated with God as His visible manifestation (v. 22). But the difference between the angel and God is highlighted by the angel being described as a “man of God” (13:6, 8) and “the man” (13:10-11).
The Angel of the Lord is also equated with God (theophany) in Gen 31:11-13; Jud 2:1; but differentiated from God as well, as a representative: (2 Sam 24:16; 1 Ki 19:6-7; 2 Ki 19:35; Dan 3:25, 28; 6:23; Zech 1:8-14).
Lot also clearly venerated two angels, who appear by the text (again, 18:22 cf. 19:1) to be the same angels whom Abraham had talked to and venerated:
They distinguish themselves from the LORD:
Genesis 19:1 The two angels came to Sodom in the evening; and Lot was sitting in the gate of Sodom. When Lot saw them, he rose to meet them, and bowed himself with his face to the earth,
Genesis 19:13 for we are about to destroy this place, because the outcry against its people has become great before the LORD, and the LORD has sent us to destroy it.”
All of this suggests that it was quite possible indeed that John could have mistaken the angel for Jesus. After all, Jesus had appeared to him earlier in the book, and when He saw Him, he “fell at his feet as though dead” (1:17; cf. 1:10-20). We also know that the post-Resurrection Jesus was not recognized for Who He was, several times (cf. Lk 24:16, 31; 36-39; Jn 20:14-18, 21:4).
In any event, since angels were venerated in the Bible in Genesis 18 and 19, by Abraham and Lot, without rebuke, we know that Revelation 19 and 22 cannot be seen as “proof” (as many hopeful Protestant commentaries claim) that such veneration is forbidden, and indeed, idolatry. Ken argues that any such veneration is too confusing, too easily descends into idolatry or is seen as such by observers; therefore, shouldn’t take place at all. Funny, then, that God in His inspired word (two times) sees it as perfectly acceptable (from Abraham, yet!) and doesn’t rebuke it in the slightest.
Moreover, angels are bowed to in the New Testament, with no rebuke at all:
Luke 24:4-5 While they were perplexed about this, behold, two men stood by them in dazzling apparel;  and as they were frightened and bowed their faces to the ground, the men said to them, “Why do you seek the living among the dead?”
Even men (apostles) are venerated in the New Testament:
Acts 16:25-31 But about midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them,  and suddenly there was a great earthquake, so that the foundations of the prison were shaken; and immediately all the doors were opened and every one’s fetters were unfastened.  When the jailer woke and saw that the prison doors were open, he drew his sword and was about to kill himself, supposing that the prisoners had escaped.  But Paul cried with a loud voice, “Do not harm yourself, for we are all here.”  And he called for lights and rushed in, and trembling with fear he fell down before Paul and Silas,  and brought them out and said, “Men, what must I do to be saved?”  And they said, “Believe in the Lord Jesus, and you will be saved, you and your household.”
No biggie. King David was venerated in the Old Testament, too:
1 Chronicles 29:20 Then David said to all the assembly, “Bless the LORD your God.” And all the assembly blessed the LORD, the God of their fathers, and bowed their heads, and worshiped [shachah] the LORD, and did obeisance [shachah] to the king. [KJV: “worshipped the LORD, and the king”]
So was Daniel (without rebuke from him):
Daniel 2:46-48 Then King Nebuchadnez’zar fell upon his face, and did homage to Daniel, and commanded that an offering and incense be offered up to him. The king said to Daniel, “Truly, your God is God of gods and Lord of kings, and a revealer of mysteries, for you have been able to reveal this mystery.”  Then the king gave Daniel high honors and many great gifts,
The king was venerating or honoring God through Daniel, as is evident by his words. This is the sort of principle elaborated even by Martin Luther:
Thus, too, I would solve the question about adoring and invoking God dwelling in the saints. It is a matter of liberty, and it is not necessary either to do it or not to do it. To be sure, it is not so certain that God has His dwelling in many men as that He is present in the sacrament, but we do read in I Corinthians [footnote: 1 Cor 14:24-25] that an unbeliever will fall on his face and worship God in the saints, if he hears them prophesying; and Abraham saw three angels, and worshiped one Lord; and (to use your own illustration) what do we do when we “prefer one another in honor,” except honor and adore God in ourselves? Let it be free, then, to call upon God in man or out of man, in creatures or out of them, for “I fill heaven and earth,” saith the Lord. Here faith goes the safest way, for in all things it sees only God, but we cannot say enough of this to unbelievers, or prove it to them, because they are always worshiping themselves.
(Letter to Paul Speratus, 13 June 1522)
Daniel venerates an angel (seemingly Gabriel) later in the chapter, without rebuke:
Daniel 8:15-17 When I, Daniel, had seen the vision, I sought to understand it; and behold, there stood before me one having the appearance of a man.  And I heard a man’s voice between the banks of the U’lai, and it called, “Gabriel, make this man understand the vision.”  So he came near where I stood; and when he came, I was frightened and fell upon my face. But he said to me, “Understand, O son of man, that the vision is for the time of the end.”
That’s now seven instances of permitted veneration of creatures: four towards angels, and three towards men; five from the Old Testament and two (one of each type) in the New Testament. The Greek for “fell down before” in Acts 16:29 is prospipto (Strong’s word # 4363). It is also used of worship towards Jesus in the following five passages:
Mark 3:11 And whenever the unclean spirits beheld him, they fell down before him and cried out, “You are the Son of God.”
Mark 5:33 But the woman, knowing what had been done to her, came in fear and trembling and fell down before him, and told him the whole truth.
Mark 7:25 But immediately a woman, whose little daughter was possessed by an unclean spirit, heard of him, and came and fell down at his feet.
Luke 8:28 When he saw Jesus, he cried out and fell down before him, and said with a loud voice, “What have you to do with me, Jesus, Son of the Most High God? I beseech you, do not torment me.”
Luke 8:47 And when the woman saw that she was not hidden, she came trembling, and falling down before him declared in the presence of all the people why she had touched him, and how she had been immediately healed.
So why didn’t Paul and Silas rebuke the jailer? I submit that it was because they perceived his act as one of veneration (which is permitted) as opposed to adoration or worship, which is not permitted to be directed towards creatures. Note that the word “worship” doesn’t appear in the above five passages, nor in Luke 24:5 or Acts 16:29, or most of the other passages above, in the RSV. When “worship” does appear in connection with a man or angel, it isn’t permitted:
Thus, we see the same in Revelation 19:10 and 22:8-9, because St. John mistakenly thought the angel was Jesus, and so tried to worship / adore the angel whom he thought was God. The same thing happens, of course, when men thought that Paul and Barnabas were Zeus and Hermes and “wanted to offer sacrifice.” They were rebuked, as mistaken (Acts 14:11-18).
Therefore, we conclude (as Catholics always have) that worship / adoration is reserved for God alone, while veneration / honor is encouraged to be offered to worthy, saintly men and the holy angels. All this is plainly seen in the Bible, in the examples above.
In the comments for his article, Ken kept up the litany of unbiblical falsehoods:
The problem is the statues and icons in a worship context. . . . I have no problem with pictures/icons for historical purposes or teaching purposes. The problem is when the RC or others bow in front of them and start talking to them and praying to them.
Thus, here are the Jews, by God’s permission and command, bowing before an “icon” made by human hands, and praying to God at the same time: exactly as Ken claimed shouldn’t be allowed, since he thinks it is “idolatry.”
But Ken might retort: “What has any of this to do with statues?” Well, the statues were the large cherubim that sat atop the ark of the covenant: representations of winged celestial beings, with feet and hands. God said that He was “enthroned” on the mercy seat on top of the ark, between the two cherubim with outstretched wings (see references above for the mercy seat; also the passage immediately above; Ps 80:1; 99:1; Is 37:16; Ezek 10:4; Heb 9:5). These were described in the detailed instructions for constructing the ark (Ex 25:18-22).
Herod’s temple didn’t have the statues, but rather, paintings of cherubim on the walls. The first Christians (and Jesus Himself) were still worshiping in the Temple (Acts 2:46; 3:1; 21:26; 22:7; 24:12, 17-18) and abiding by Jewish rituals. The sacrifices were still being made there.
The Jews also worshiped God via the images of clouds (Ex 33:8-10) and fire (2 Chron 7:1-4): all expressly sanctioned by God and not condemned at all.
Ken’s assertions are, therefore, decisively refuted from Scripture at every turn.
