Take away the authority of the Church, and neither Divine Revelation nor natural reason itself is of any use, for each of them may be interpreted by every individual according to his own caprice … Do they not see that from this accursed liberty of conscience has arisen the immense variety of heretical and atheistic sects? … I repeat: if you take away obedience to the Church, there is no error which will not be embraced.
—St. Alphonsus Liguori
Liberty of conscience as it relates to salvation being imposed — Yes, naturally. You are not forced to believe.
Liberty of conscience as it relates to obtaining salvation — No such thing. Salvation is a Catholic thing.
