Father Son Holy Spirit ( NO other)
I would like to say this is a fine example of when a doctrine is
implicitly mentioned in Scripture but required Apostolic
(unwritten) Tradition to fully understand and teach.
The doctrine of the Trinity is encapsulated in Matthew 28:19, where
Jesus instructs the apostles to "go therefore and make disciples of
all nations, baptizing them in the name of the Father and of the
Son and of the Holy Spirit" and it appears elsewhere in the New
Testament (e.g., 2 Cor. 13:14; Heb. 9:14).

Church Fathers who were taught by the
Apostles:
The Didache
After the foregoing instructions, baptize in the name of the
Father, and of the Son, and of the Holy Spirit, in living [running]
water. . . . If you have neither, pour water three times on the
head, in the name of the Father, and of the Son, and of the Holy
Spirit (Didache7:1 [A.D. 70]).
Ignatius of Antioch
For our God, Jesus Christ, was conceived by Mary in accord with
God's plan: of the seed of David, it is true, but also of the Holy
Spirit (Letter to the Ephesians 18:2 [A.D. 110].
Justin Martyr
We will prove that we worship him reasonably, for we have learned
that he is the Son of the true God himself, that he holds a second
place, and the Spirit of prophecy a third. For this they accuse us
of madness, saying that we attribute to a crucified man a place
second to the unchangeable and eternal God, the Creator of all
things, but they are ignorant of the mystery that lies therein
(First Apology 13:56 [A.D. 151]).
Theophilus of Antioch
It is the attribute of God, of the most high and almighty and of
the living God, not only to be everywhere, but also to see and hear
all, for he can in no way be contained in a place. . . . The three
days before the luminaries were created are types of the Trinity:
God, his Word, and his Wisdom (To Autolycus 2:15 [A.D. 181]).
Irenaeus
For the Church, although dispersed throughout the whole world even
to the ends of the earth, has received from the apostles and their
disciples the faith in one God, the Father Almighty . . . and in
one Jesus Christ, the Son of God, who became flesh for our
salvation; and in the Holy Spirit (Against Heresies 1:10:1 [A.D.
189]).
