“There came out from his side water and blood.” Beloved, do not pass this mystery by without a thought. For I have still another mystical explanation to give. I said that there was a symbol of baptism and the mysteries in that blood and water. It is from both of these that the church is sprung “through the bath of regeneration and renewal by the Holy Spirit,” through baptism and the mysteries. But the symbols of baptism and the mysteries, water and blood, come from the side of Christ. It is from his side, therefore, that Christ formed his church, just as he formed Eve from the side of Adam.
