It's very simple. If I tell you the price of a hot dog is five hundred dollars, it doesn't matter if it's hiway robbery, it will take your last dime, you're starving... you can bitch, moan, and complain but if you take the hot dog, you have accepted my price.
Peter had very compelling reasons, but according to the dictates of Keyes faith, he was still responsible for the triple denial of Christ. Should Keyes seek to dilute his own understanding and conviction in similar circumstances?
As for you qualifiers (don't agree or approve), they are meaningless in the sense that they make no substantive difference from your full agreement with your daughter (while retaining your own personal preferences). If it walks like a duck, talks like a duck, and swims like a duck, it is disingenuous to call it anything other than a duck.
Even after the triple denial, Christ still loved Peter, and did not reject him.
In fact, according to the dictates of Keyes' faith, Christ still set Peter as the head of His church.
Let me get this straight. You're trying to claim that maintaining relations with someone equates to complete and total acceptance of their lifestyle? You don't have children do you?
