Saint Augustine of Hippo

Whatever was done, therefore, in the crucifixion of Christ, his burial, his resurrection on the third day, his ascension into heaven, his being seated at the Father’s right hand – all these things were done thus, that they might not only signify their mystical meanings but also serve as a model for the Christian life which we lead here on the earth. Thus, of his crucifixion it was said, “And they that are Jesus Christ’s have crucified their own flesh, with the passions and lusts thereof” ; and of his burial, “For we are buried with Christ by baptism into death”; of his resurrection, “Since Christ is raised from the dead through the glory of the Father, so we also should walk with him in newness of life”; of his ascension and session at the Father’s right hand: “But if you have risen again with Christ, seek the things which are above, where Christ is sitting at the right hand of God. Set your affection on things above, not on things on the earth. For you are dead, and your life is hid with Christ in God.”
