Do not confuse what a true Christian is...So when Paul called Peter on the carpet, ( Gal 2 ), should he have followed the opening poster's
recommendation "that we Christians be a bit more tolerant about our differences" ?
For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and overcome, the latter end is worse for them than the beginning. 21 For it would have been better for them not to have known the way of righteousness, than having known it, to turn from the holy commandment delivered to them. 22 But it has happened to them according to the true proverb: “A dog returns to his own vomit,” and, “a sow, having washed, to her wallowing in the mire.” 2 Peter 2
With being true to Christianity.
What is a true Christian? One who believed in Jesus Christ.
What is being a true Christian who is true to Christianity?
Well? Peter was a true Christian when Paul chewed him out for not being true to Christianity.
Some would have said Peter was not really saved.
Maybe even you would have thought that at that time.
