irit, which is the word of God. And, being thus excellently
armed and guarded on every side, in this confidence go forth to the
warfare against ungodliness, until, this put to flight, and its prince,
the devil, dashed headlong to the earth, thou be adorned with the
crowns of victory from the right hand of thy master, the Lord of life."

With such like doctrines and saving words did Barlaam instruct the
king's son, and fit him for holy Baptism, charging him to fast and
pray, according to custom, several days: and he ceased not to resort
unto him, teaching him every article of the Catholick Faith and
expounding him the holy Gospel. Moreover he interpreted the Apostolick
exhortations and the sayings of the Prophets: for, taught of God,
Barlaam had alway ready on his lips the Old and New Scripture; and,
being stirred by the Spirit, he enlightened his young disciple to see
the true knowledge of God. But on the day, whereon the prince should be
baptized, he taught him, saying, "Behold thou art moved to receive the
seal of Christ, and be signed with the light of the countenance of the
Lord: and thou becomest a son of God, and temple of the Holy Ghost, the
giver of life. Believe thou therefore in the Father, and in the Son,
and in the Holy Ghost, the holy and life-giving Trinity, glorified in
three persons and one Godhead, different indeed in persons and personal

the Father; and one begotten Lord, the Son, light of light, very God of

whom all things, visible and invisible, were made: knowing also one
Holy Ghost, which proceedeth from the Father, perfect, life-giving and
sanctifying God, with the same will, the same power, coeternal and
impersonate. Thus therefore worship thou the Father, and the Son, and
the Holy Ghost, in three persons or properties and one Godhead. For
the Godhead is common of the three, and one is their nature, one their
substance, one their glory, one their kingdom, one their might, one
their authority; but it is common of
