J. Edwards,

It makes sense that individuals mature in their writings. There is much divergence obviously among theologians. ... and transpiring while the Church(es) use the term 'development of doctrine' (over hundreds of years)... including Catholicism (RCC). Augustine wisely said, for instance, concerning his own development on the subject of persecution:

...but, moreover, from being a persecutor, he suffered persecution in defence of that faith which he persecuted. Because it was given him by Christ “not only to believe on Him, but also to suffer for His sake.”

-- and I have to also wonder about Calvin, who did not seem to get this in his maturity... and I know that there are different sources saying different things about this topic... I do not believe anyone can prove the truth of the matter... but I think it matters... very much.

Thank you for your input.
