Whether it was fitting that God should become incarnate in the beginning of the human race?

Objections

Objection 1 : It would seem that it was fitting that God should become incarnate in the beginning of the human race. For the work of the Incarnation sprang from the immensity of Divine charity, according to Eph. 2:4,5: "But God (Who is rich in mercy), for His exceeding charity wherewith He loved us . . . even when we were dead in sins, hath quickened us together in Christ." But charity does not tarry in bringing assistance to a friend who is suffering need, according to Prov. 3:28: "Say not to thy friend: Go, and come again, and tomorrow I will give to thee, when thou canst give at present." Therefore God ought not to have put off the work of the Incarnation, but ought thereby to have brought relief to the human race from the beginning.
Objection 2 : Further, it is written (1 Tim. 1:15): "Christ Jesus came into this world to save sinners." But more would have been saved had God become incarnate at the beginning of the human race; for in the various centuries very many, through not knowing God, perished in their sin. Therefore it was fitting that God should become incarnate at the beginning of the human race.
Objection 3 : Further, the work of grace is not less orderly than the work of nature. But nature takes its rise with the more perfect, as Boethius says (De Consol. iii). Therefore the work of Christ ought to have been perfect from the beginning. But in the work of the Incarnation we see the perfection of grace, according to Jn. 1:14: "The Word was made flesh"; and afterwards it is added: "Full of grace and truth." Therefore Christ ought to have become incarnate at the beginning of the human race.
