Behold the happy time is come which was called the designated time: “When the designated time had come, God sent his Son…to deliver from the law those who were subjected to it” (Gal 4:4). It is called the fullness of time because of the fullness of grace which the Son of God came to communicate to [us] by the redemption of the world.
— St Alphonsus Liguori
