Someone on Reddit asked about Christian agnosticism, leading me to write the following (on which I based the quote in the image above, slightly modified to make better sense outside of its original context.
A lot of commenters here seem to reflect the mistaken view that faith means feeling certain about something despite there not being sufficient rational grounds. But faith in the Christian sense (on which I recommend reading Paul Tillich’s Dynamics of Faith) means doing what the Bible tells us to, namely recognizing our own human limitations, and that we are not God, and that we must trust God precisely because of our inability to be absolutely certain, and our penchant for being wrong despite feeling certain.
One cannot be a Christian and not be an agnostic in this sense of the word.
I also wrote the following a while back, in response to someone who had experienced multiple personal tragedies and asked me what view of the world seems cogent to me:
For me the most cogent thing is a humble religious agnosticism that acknowledges that there is an ultimate Reality of some sort, but also recognizes that my perception and comprehension is exhausted long before I get anywhere near to fathoming that Reality.
You also cannot be a Christian without questioning the Bible. The Bible includes positive depictions of the slaughter of Canaanites and the calling down of fire on enemies (which Jesus challenged), and demands such as that all members of Abraham’s household be circumcised (which Paul challenged).
