The Pope has always had the charisma of infallibility. This was explicitly defined by Vatican 1 but not created by Vatican 1. Otherwise we could not hold as certain anything before Vatican 1, which is plainly untrue.
Further, as I cited earlier: Pope Pius X condemed the error that:
“When the Church proscribes errors, she cannot exact any internal assent of the faithful, by which the judgments published by her are embraced.”
(Denzinger 2007 7)
Which means that the Church can proscribe errors, and the Faithful are bound to internal assent of these proscriptions.
I am not “picking fights” but simply explaining the Church teaching. And no matter how you, me, or anyone else feels about it, when the Church speaks definitively the case is closed. You can argue all you want, but at the end of the day, you are required to assent. It seems now that you want this to be a situation where we get to talk about it and decide for ourselves which course is best. This is a flawed thinking. There can be no more debate once the authority has declared a definitive answer.
Passionate kissing (making out) for the unmarried is gravely illicit. To willingly engage in this behavior is mortal sin. This has always been and will always be, and cannot be changed by man nor angel.
