Whether all the sacraments are necessary for salvation?

❌ Objection 1 : It seems that all the sacraments are necessary for salvation. For what is not necessary seems to be superfluous. But no sacrament is superfluous, because "God does nothing without a purpose" (De Coelo et Mundo i). Therefore all the sacraments are necessary for salvation.

❌ Objection 2 : Further, just as it is said of Baptism (Jn. 3:5): "Unless a man be born again of water and the Holy Ghost, he cannot enter in to the kingdom of God," so of the Eucharist is it said (Jn. 6:54): "Except you eat of the flesh of the Son of Man, and drink of His blood, you shall not have life in you." Therefore, just as Baptism is a necessary sacrament, so is the Eucharist.

❌ Objection 3 : Further, a man can be saved without the sacrament of Baptism, provided that some unavoidable obstacle, and not his contempt for religion, debar him from the sacrament, as we shall state further on (Question [68], Article [2]). But contempt of religion in any sacrament is a hindrance to salvation. Therefore, in like manner, all the sacraments are necessary for salvation.
