"Apostasy from the Catholic Church imperils one's salvation, that is what the Church teaches and has always taught. Of course it may not be congruent with your own personal magisterium. You are continually telling us that you subject Catholic doctrine to the test of your own intellect and accept it or reject it according to your own lights, which renders what you believe no more than a personal, individual credo."
"Are you seriously proposing that apostasy from the Catholic Faith has no eternal consequences? If you are then let's have some back up and not just careful selections from various Church documents. When has the Church ever condoned apostasy."
Here is what Vatican ll teaches.
"Whosoever knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved." Lumen Gentium 14.
