Bellarmine, Alphonsus, Pius IX and Pius XII should have consulted you on the proper interpretation of Trent.
And you really believe the erred or did not teach what they taught. This is mind-boggling. You have been sufficiently brain-washed unless it is a damnable willful blindness you have.
When Trent says "If any one saith that baptism is optional, that is, not necessary unto salvation; let him be anathema." All that really matter is that because YOU say "the sacrament is optional", that is, YOU say "the sacrament is not necessary unto salvation", per Trent, YOU are anathema.
Do you understand that much, or do you honestly need one of the Church Fathers to interpret that for you too?
At any rate, as I said, same o same o - you asked a question, I gave you the answer quoted directly from Trent, you keep trying to prove Trent is wrong. Wash, rinse, repeat.
