You have heard the lesson from the holy Gospel on the Resurrection of Christ. Our faith has been established on the Resurrection of Christ. Pagans, wicked people, and Jews believed in the Passion of Christ; Christians alone believe in His Resurrection. The Passion of Christ discloses the miseries of this life; the Resurrection of Christ points to the happiness of the life to come. At present, let us labor; let us hope for the future. Now is the time for work; then, for reward. He who is lazy in doing his work here is shameless if he demands recompense. You have heard what the Lord said to His disciples after the Resurrection. He sent them to preach the Gospel and they carried out His command; the Gospel was preached; it has come to us. Behold: ‘Their sound hath gone forth into all the earth: and their words unto the ends of the world.’ By one journey after another the Gospel came to us and to the farthest limits of our country. In a few words the Lord sketched His plan for us, telling His disciples what we were to do and what we were to hope for. As you heard when the Gospel was read, He said: ‘He who believes and is baptized shall be saved.’ Faith is demanded of us; salvation is offered to us. ‘He who believes and is baptized shall be saved.’ Precious is the gift which is promised to us; what is bidden is fulfilled without cost.
Augustine of Hippo, Sermons for the Easter Season 233.1
Christ descended into hell to liberate its captives. In one instant He destroyed all record of our ancient debt incurred under the law, in order to lead us to heaven where there is no death but only eternal life and righteousness. By the baptism which you, the newly enlightened, have just received, you now share in these blessings. Your initiation into the life of grace is the pledge of your resurrection. Your baptism is the promise of the life of heaven. By your immersion you imitated the burial of the Lord, but when you came out of the water you were conscious only of the reality of the resurrection.… The grace of the Spirit works in a mysterious way in the font, and the outward appearance must not obscure the wonder of it. Although water serves as the instrument, it is grace which gives rebirth. Grace transforms all who are placed in the font as the seed is transformed in the womb. It refashions all who go down into the water as metal is recast in a furnace. It reveals to them the mysteries of immortality; it seals them with the pledge of resurrection. These wonderful mysteries are symbolized for you, the newly enlightened, even in the garments you wear. See how you are clothed in the outward signs of these blessings. The radiant brightness of your robe stands for incorruptibility. The white band encircling your head like a diadem proclaims your liberty. In your hand you hold the sign of your victory over the devil. Christ is showing you that you have risen from the dead. He does this now in a symbolic way, but soon He will reveal the full reality if we keep the garment of faith undefiled and do not let sin extinguish the lamp of grace. If we preserve the crown of the Spirit, the Lord will call from heaven in a voice of tremendous majesty, yet full of tenderness: Come, blessed of my Father, take possession of the kingdom prepared for you since the beginning of the world. To him be glory and power for ever, through endless ages, amen.
Basil of Seleucia, Easter Homily
