The Purifying Power of Baptism

He's talking about baptismal regeneration. The forgiveness of sins that the prophet isaiah talked about, all of this is about bap ism. He returns a son of god and joint heir with christ. Is a beautiful quote, but it doesn't prove what doctor ortland is trying to demonstrate from this. I've never heard of people thinking of circumcision working ex opera operato to convey all the blessings it symbolizes.
