the waters we obtain the Holy Spirit; but in the water, under (the witness of) the angel, we are cleansed, and prepared for the Holy Spirit. In this case also a type has preceded; for thus was John beforehand the Lord's forerunner, "preparing His ways."  Thus, too, does the angel, the witness  of baptism, "make the paths straight"  for the Holy Spirit, who is about to come upon us, by the washing away of sins, which faith, sealed in (the name of) the Father, and the Son, and the Holy Spirit, obtains. For if "in the mouth of three witnesses every word shall stand:"  -- while, through the benediction, we have the same (three) as witnesses of our faith whom we have as sureties  of our salvation too -- how much more does the number of the divine names suffice for the assurance of our hope likewise! Moreover, after the pledging both of the attestation of faith and the promise  of salvation under "three witnesses," there is added, of necessity, mention of the Church;  inasmuch as, wherever there are three, (that is, the Father, the Son, and the Holy Spirit, ) there is the Church, which is a body of three. 
 Compare c. viii., where Tertullian appears to regard the Holy Spirit as given after the baptized had come out of the waters and received the "unction."  Luke 1:76.  Sponsores.  Sponsio.  Compare de Orat. c. ii. sub fin.  Compare the de Orat. quoted above, and de Patien. xxi.; and see Matthew 18:20.
