I am almost never asked, “Right Reverend Crip Dyke, if some community leader is going to be a self-professed Christian, would you prefer that person be an honest believer or would you rather that person be a nominal Christian that clearly doesn’t believe in the actual teachings of the bible?”
However, that question is clearly asked or implied on the internet many, many times per day. Some think that the believing Christian is harder to reform because they really do believe on faith many non-sensical things that come straight out of the New Testament, the Tanakh, or the ancillary writings included in the Christian “Old Testament”. Often times this carries a presumption that I (really: the random internet atheist subject to the question) will prefer the person easier to deconvert.
