[Luddite Patent Counsel]

After his decision to follow Christ, Peter and his wife "became as brother and sister". That was the second model for pristly celibacy, after Christ himself.

After his decision to follow Christ, Peter and his wife "became as brother and sister".

That's apocryphal. Are you getting that from the Gospel of Thomas?

What source are you relying on? Paul, in 1 Tim. 4:3, considered it part of the great apostasy to forbid marriage. That doesn't include voluntary singlness, which is commended. I can't find in scripture, or any other source close enough to the time that teaches that Peter stoped having relations with his wife.
