Content: Then Philip said, “If you believe with all your heart, you may.” ; And he answered and said, “I believe that Jesus Christ is the Son of God.” This verse is absent from the majority of the Greek manuscripts, but it is present in some, including E (6th or 7th century). It is cited by Irenaeus (c. 180) and by Cyprian (c. 250), and is found in the Old Latin (2nd/3rd century) and the Vulgate (380–400) translations. In his notes Erasmus says that he took this reading from the margin of 4ap and incorporated it into the Textus Receptus. J. A. Alexander (1857) suggested that this verse, though genuine, was omitted by many scribes, "as unfriendly to the practice of delaying baptism, which had become common, if not prevalent, before the end of the 3rd century."
