St. Thomas Aquinas, Summa Theologica III, Q. 68, Art. 2: “... it seems that a man
can obtain salvation without the sacrament of Baptism, by means of the invisible
sanctification...”
Pope Paul III, The Council of Trent, Can. 5 on the Sacrament of Baptism, Sess. 7,
1547, ex cathedra: “If anyone says that baptism [the sacrament] is optional, that
is, not necessary for salvation (cf. Jn. 3:5): let him be anathema.”
who should I believe here, St Thomas or the Pope?
