Remember, then, that you received a spiritual seal, the spirit of wisdom and understanding, the spirit of knowledge and reverence, the spirit of holy fear. Keep safe what you received. God the Father sealed you, Christ the Lord strengthened you and sent the Spirit into your hearts as the pledge of what is to come.
AmbroseThe Lord was Baptized, not to be cleansed Himself, but to cleanse the waters, so that those waters, cleansed by the flesh of Christ which knew no sin, might have the power of Baptism.
