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.
