The same significance is attributed to the trine immersion by many Fathers, but a different explanation is given by Tertullian (Adv. Praxean, c. xxvi.): “Not once only, but three times, we are immersed into the several Persons at the mention of their several names.” Gregory of Nyssa (On the Baptism of Christ, p. 520 in this Series) joins both reasons together: “By doing this thrice we represent for ourselves that grace of the Resurrection which was wrought in three days: and this we do, not receiving the Sacrament in silence, but while there are spoken over us the Names of the Three Sacred Persons on whom we believed, &c.” Compare p. 529. Cf. Apost. Const VIII. § 47, Can. 50: “If any Bishop or Presbyter does not perform the three immersions of one initiation, but one immersion made into the death of Christ, let him be deprived.” Milles in his note on this passage mentions that “this form of Baptism is still used in the Greek Church. See Eucholog. p. 355. Ed. Jac. Goar. and his notes p. 365.”
