[in final version: 2051 Bible Passages entirely written out: KJV with RSV alternate versions added where necessary to clarify meaning]


Doubtless, were only the Scripture allowed its own authority, there are none of these things respecting which our adversaries would not be constrained to be mute. . . . Though they may kiss the closed copies of the Scripture as a kind of worship, . . . they allow it no more authority than if no part of it existed in writing.

— John Calvin, dedication of his Commentary on the General Epistles, January 1551

The aim of this book is very simple (hence the short introduction), and it reflects much of the emphasis in my Catholic apologetic efforts for the last 18 years. I want to provide the biblical rationale for Catholic beliefs. The subject matter is as endless as the riches, wisdom, and depths of the Bible itself.


My immediate goal is to simply present categorized Bible passages. My own commentary will be kept to a minimum and used only in instances where I am straightforwardly reiterating what Holy Scripture itself states, noting relevant contextual considerations, Greek or Hebrew meanings of words (as explicated by linguistic scholars), or scriptural cross-references.

I have, of course, selected the passages and classified them. Insofar as I did that, I was engaging in “systematic theology.” Human input (something beyond God’s own words) is necessary as soon as one goes beyond simply placing a Bible on a table in front of someone and saying, “read all of this: it completely supports what Catholics teach.” In all reasonable argumentation whatever, selective presentation takes place, and in systematic theology, it is necessary to locate the relevant biblical texts and to collect them for the purpose of illustrating that “the Bible teaches thus and so about this particular topic.” And that involves judgment, which in turn includes a bias.

In that sense, this book is not just the Bible. My input and editing and orthodox Catholic presuppositions are present. But the central, essential focus is “just the Bible.” Holy, Sacred Scripture is thoroughly “Catholic,” as I hope to demonstrate in great detail. Praise God for His wonderful, materially sufficient revelation and His aid in helping us to understand and live by it.

Some Catholic teachings are less well-attested by direct scriptural indications than others. Yet I believe that those doctrines are also “soaked” in the spirit of the Bible. The comprehensive selection of texts herein repeatedly demonstrates this, in my opinion. A multitude of pointers can be as compelling as a single unambiguous signpost, to show us our way. Readers are free to decide the relative strength of individual textual evidence.

Reading these extracts in their full context is even more rewarding and illuminating. The Bible is a harmonious whole: “living and active”, and should be interpreted as such, rather than picked apart into fragments. For the purpose of systematic doctrinal study, however, it is quite helpful to categorize texts. Moreover, Catholics emphasize that the Bible is organically related to the tradition and the Church in which it is received and interpreted. If this book helps readers to move beyond arguments into a deeper appreciation of the Word of God, in which lies our salvation, I will be more than happy.

For my purposes in this work, I’ve chosen the Authorised (King James Version) of the Bible, due to its familiarity among Protestants. Its lofty, poetic prose is deeply embedded in the heritage of English literature and thinking, and Catholic readers will also find it inspiring. In cases of archaic expression, I have clarified in parentheses with the Revised Standard Version: one of the most accurate and beloved modern translations.

Lastly, Catholics and Protestants notoriously disagree as to which books constitute the biblical canon. The number of the inspired books accepted by the universal Church prior to the onset of Protestantism was disputed by Martin Luther and other non-Catholic Christians, and seven books were eventually omitted altogether in most Protestant editions of the Bible, or included separately as sub-canonical “apocryphal” texts. Some of these refer directly to distinctively Catholic doctrines (most notably, purgatory). I’ve included relatively few citations from these “disputed” books, but for the Catholic, they are Scripture, too, and ought not be excluded. If the non-Catholic reader wishes to pass over them, more than ample texts remain as “evidences.”
