Whether insincerity hinders the effect of Baptism?

❌ Objection 1 : It seems that insincerity does not hinder the effect of Baptism. For the Apostle says (Gal. 3:27): "As many of you as have been baptized in Christ Jesus, have put on Christ." But all that receive the Baptism of Christ, are baptized in Christ. Therefore they all put on Christ: and this is to receive the effect of Baptism. Consequently insincerity does not hinder the effect of Baptism.

❌ Objection 2 : Further, the Divine power which can change man's will to that which is better, works in Baptism. But the effect of the efficient cause cannot be hindered by that which can be removed by that cause. Therefore insincerity cannot hinder the effect of Baptism.

❌ Objection 3 : Further, the effect of Baptism is grace, to which sin is in opposition. But many other sins are more grievous than insincerity, which are not said to hinder the effect of Baptism. Therefore neither does insincerity.
