"The Lord has given us baptism in the place of circumcision; his blood and flesh in place of the lambs’ flesh…Circumcision is circumcision of the heart by the spirit…It is not the same, nor even the circumcision [itself]. Rather, it is the cleanliness and the purification of the heart in the Holy Spirit by means of baptism."

(Būlus al-Būshī, Commentary on the Apocalypse of John 1-3)
