Whether certain acts of the virtues are fittingly set down as effects of Baptism, to wit---incorporation in Christ, enlightenment, and fruitfulness?

Objections

Objection 1 : It seems that certain acts of the virtues are unfittingly set down as effects of Baptism, to wit---"incorporation in Christ, enlightenment, and fruitfulness." For Baptism is not given to an adult, except he believe; according to Mk. 16:16: "He that believeth and is baptized, shall be saved." But it is by faith that man is incorporated in Christ, according to Eph. 3:17: "That Christ may dwell by faith in your hearts." Therefore no one is baptized except he be already incorporated in Christ. Therefore incorporation with Christ is not the effect of Baptism.
Objection 2 : Further, enlightenment is caused by teaching, according to Eph. 3:8,9: "To me the least of all the saints, is given this grace . . . to enlighten all men," etc. But teaching by the catechism precedes Baptism. Therefore it is not the effect of Baptism.
Objection 3 : Further, fruitfulness pertains to active generation. But a man is regenerated spiritually by Baptism. Therefore fruitfulness is not an effect of Baptism.
