PROLOGUE

Forasmuch as our Saviour the Lord Jesus Christ, in order to "save His
people from their sins" (Matt. 1:21), as the angel announced, showed
unto us in His own Person the way of truth, whereby we may attain to
the bliss of eternal life by rising again, it is necessary, in order
to complete the work of theology, that after considering the last end
of human life, and the virtues and vices, there should follow the
consideration of the Saviour of all, and of the benefits bestowed by
Him on the human race.

Concerning this we must consider (1) the Saviour Himself; (2) the
sacraments by which we attain to our salvation; (3) the end of
immortal life to which we attain by the resurrection.

Concerning the first, a double consideration occurs: the first, about
the mystery of the Incarnation itself, whereby God was made man for
our salvation; the second, about such things as were done and
suffered by our Saviour--i.e. God incarnate.

(2) Whether it was necessary for the restoration of the human race?

(3) Whether if there had been no sin God would have
