13 To become a member of Holy Church by baptism is to be clothed in the beauty with which Christ adorns His beloved Bride. "Christ loved the Church and delivered Himself up for her; that he might sanctify her, cleansing her in the bath of water by means of the word of life; in order that he might present to himself the Church in all her glory, not having spot or wrinkle or any such thing; but that she might be holy and without blemish."(13)
