"I receive Thee, redeeming Prince of my soul. Out of love for Thee have I studied, watched through many nights, and exerted myself: Thee did I preach and teach. I have never said aught against Thee. Nor do I persist stubbornly in my views. If I have ever expressed myself erroneously on this Sacrament, I submit to the judgement of the Holy Roman Church, in obedience of which I now part from this world." Saint Thomas Aquinas the greatest Doctor of the Church
As we know, Trent infallibly judged that the sacrament of baptism is necessary for salvation, that whoever says the sacrament is optional, like Lover of Liberalism constantly does, is anathema.
Unlike Lover of Liberalism, the greatest theologian and Doctor, St. Thomas, by his own words, submits to this judgement.
