"1 Tim 4:3 forbidding to marry, and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth."
How is this in any way relevant? The Church has never forbidden anyone to marry as long as they have been free to marry.
Neither does the above passage have any relevance to fasting which was encouraged by Jesus Christ - I suppose He was unscriptural as well, was He?
I'd like to simply say that forbidding a priest to marry is exactly what 1Tim is talking about but I can't say it that simply because the RC priesthood is unscriptural. Lets pretend that an RC "priest" is really just a misguided Christian who wants to enter into the ministry, forbidding him to marry is completely wrong.
