So, before presenting the concept of the biblical
doctrine of the Trinity to Muslims (or any other
anti-Trinitarian group) you must first deal with the
unitarian/unipersonal assumption: i.e., God existing as
one Person. For this is the theological starting
point of groups such as Muslims, Jews, Jehovah’s
Witnesses, Oneness Pentecostals, etc. It must be
emphasized over and over: The very foundation of the
doctrine of Trinity is ontological Monotheism—one God
by nature (cf. Deut. 6:4; Jer. 10:10-11.)
The 3 Pillars of the Trinity
There is only one God.
There are three Persons or Selves that are presented as
God: the Father, the Son and the Holy Spirit.
The three Persons are
from each other.
The three distinct Persons share the
same nature or Being of the one God.
Scripture presents that
Jesus Christ was God and Worshiped as God
1. Jesus is God
(ho theos, “the God) and seen as the YHWH of the
Titus 2:13 and 2

Grammar Rule #1);
was presented as the great “I Am” (egō eimi);
viz. at John 8:24, 28, 58; 13:19; 18:5, 6, and 8 (see
2. He was
presented as the YHWH of the OT.
authors clearly envisaged Jesus Christ as the Yahweh of
the OT. Hence, they often cited OT passages referring to
Yahweh and applied them to Jesus Christ: e.g., compare
Joel 2:32 with Rom. 10:13; Isa. 6:8 with John 12:41;
Ps. 102-25-27 with Heb. 1:10; Isa. 45:23-24 with
Phil. 2:9-11; Isa. 8:12, 13 with 1 Pet. 3:14, 15; etc.
Jesus is Jehovah:
Old Testament passages of Jehovah applied specifically
to Jesus Christ in the New Testament).
3. Jesus is
e.g., John 1:3;
Heb. 1:2, 8-10.
The Preexistence of Jesus Christ in
the Face of Unitarianism
claimed He was fully God:
Although Jesus never literally stated, "I am God,"
Jesus’ claims to deity were much stronger and clearer
than if He had said, “I am God.” In fact, some of
Jesus' claims to deity were only used of YHWH
John 10:26-33 (cf. Duet. 32:39; Ps. 95:7);
the seven “I Am” (egō eimi) affirmations
stated at John 8:24, 28, 58; 13:19; 18:5, 6, and 8.
5. Jesus is
worshiped in a “religious context” which was reserved
for God alone
(cf. Exod. 20:5): e.g., Dan 7:14; Matt. 14:33; 28:9;
John 9:38; Heb. 1:6; Rev. 5:11-14.-- See
Christ Worshiped as God
possesses the SAME attributes as God the Father,
(cf. John 1:3; Col. 1:16-17; Heb. 1:10-12)
Raises the dead
and gives them life: John 5:21: "For just as the
Father raises the dead and gives them life, even so the
Son also gives life to whom He wishes” (cf. John
(cf. Matt. 28:20; John 14:23; 2 Cor. 13:5; Gal. 2:20).
(cf. John 2:24-25; 6:64; 16:30; 21:17).
Omnipotent or all-powerful
(cf. Matt. 8:27; 9:6; 28:18; Heb. 7:25).
(Pre-Existing) (cf. Micah 5:2; John 1:1; 8:58;
(cf. Heb. 13:8).
To recap, Scripture then presents in the clearest way
that Jesus Christ is God (yet distinct from the
Father, cf. John 1:1b; 17:5), Creator,
worshipped in a religious context, and possesses
the same attributes as that of God the Father.
III. The Holy Spirit is God:
e.g., Acts 5:3-4; the Holy Spirit also possesses
the attributes of God:
having neither beginning nor end (cf. Heb. 9:14),
being everywhere at the same time (cf. Ps. 139:7).
understanding all things (cf. 1 Cor. 2:10-11).
(cf. Luke 1:35).
The Holy Spirit is a Person:
e.g., the Holy Spirit communicates (e.g., Acts
10:19-20; 13:2; Heb. 3:7-11; 10:15-17);
personal pronouns (“I,” “He”) are applied to Him
(cf. Acts 10:20; John 16:13-14); possesses “personal”
attributes (e.g., He has a will [cf. 1
Cor. 12:9-11]; emotions [cf. Eph. 4:30];
intelligence in that He investigates [cf.
1 Cor. 2:10-11; Rom. 8:27]; He intercedes/prays [cf.
Rom. 8:26]; He can be lied to [cf. Acts 5:3]; He can be
blasphemed [cf. Mark 3:29-30]; He issues commands [cf.
Acts 13:4; Acts 16:6]; He gives love [cf. Rom. 15:30]).
God the Holy Spirit:
The Third Person of the Trinity
The three Persons are distinct from each other:
e.g., John 1:1b. 17:5; Matt. 28:19; 1 Cor. 13:14;
1 John 1:3; Rev. 5:13.
Additionally, in the OT, God is presented as
multi-Personal: e.g., Gen. 19:24; Isa. 48:16; Hosea
1:7; Eccl. 12:1 (Heb. “Creators”); Isa. 54:5 (Heb.
“Makers”; see also:
God in the Old Testament and Oneness Theology)
conclusion then, Scripture presents a tri-personal
God. The Trinity is God’s highest revelation to
Jesus told the Samaritan woman that God seeks those who
worship Him “in spirit and truth.” In truth, God is
triune. Worshipping a unipersonal God or three separate
Gods is not worshipping Him in truth. The issue being
that the truth of the Trinity, the
self-disclosure of God to men, is found in nearly every
page of the Holy Scriptures: There is one God, and
there are three distinct, coequal, coeternal, and
coexistent, self-cognizant divine Persons or Egos that
share the nature of the one God—the Father, the Son, and
the Holy Spirit.
Trinity and the Early Church: Debunking the Oneness
Historically, these verses are no doubt
referring to a heretical so-called Christian
sect called Mariyama or Collyridians who existed
within the same geographical location and period
as that of Mohammad. This sect held to a form of
Tritheism, worshipping Mary and her Son both of
which were believed to be two separate gods
