Whether grace and virtues are bestowed on man by Baptism?

Objections

Objection 1 : It seems that grace and virtues are not bestowed on man by Baptism. Because, as stated above (Question [62], Article [1], ad 1), the sacraments of the New Law "effect what they signify." But the baptismal cleansing signifies the cleansing of the soul from guilt, and not the fashioning of the soul with grace and virtues. Therefore it seems that grace and virtues are not bestowed on man by Baptism.
Objection 2 : Further, one does not need to receive what one has already acquired. But some approach Baptism who have already grace and virtues: thus we read (Acts 10:1,2): "There was a certain man in Cesarea, named Cornelius, a centurion of that which is called the Italian band, a religious man and fearing God"; who, nevertheless, was afterwards baptized by Peter. Therefore grace and virtues are not bestowed by Baptism.
Objection 3 : Further, virtue is a habit: which is defined as a "quality not easily removed, by which one may act easily and pleasurably." But after Baptism man retains proneness to evil which removes virtue; and experiences difficulty in doing good, in which the act of virtue consists. Therefore man does not acquire grace and virtue in Baptism.
