and you’ll lose your soul!” With this in mind, let’s examine 10 things we should all know about the Trinity.
(1) We must never forget that our knowledge of God is a gift, not a given. What I mean by this is that we all too often presume that what we know of God is either something we gained by self-exertion, dedication, and study, or it is something we deserve, perhaps something that is our by right or entitlement. We should never treat the knowledge of God as a given. It is something he gives, and he does not give it universally. This is nowhere better seen in our Lord’s words in Matthew 11.
At that time Jesus declared, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will. All things have been handed over to me by my Father, and no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him. (Matthew 11:25-27)
When the Father finally makes sense to us, when we come to know him truly, to the degree that we grasp something of his nature and will and ways, it is because the Son has graciously stooped to reveal him to us. Our knowledge of God does not come naturally. Neither is it ultimately the product of meticulous research or study. It certainly isn’t because we deserve it. It’s a gift from his Son. He and he alone is the mediator of the knowledge of God to mankind. If one is to know the Son the Father must reveal him. If one is to know the Father the Son must reveal him. It takes God to know God!
(2) The concept of the one God as a trinity of co-equal, yet distinct, persons is the most intellectually taxing and baffling doctrine in Scripture. It is a mystery that is beyond reason yet not contrary to it. Probably the most famous definition of the doctrine of the Trinity is that of St. Augustine (4th-5th century a.d.):
“There are the Father, the Son, and the Holy Spirit, and each is God, and at the same time all are one God; and each of them is a full substance, and at the same time all are one substance. The Father is neither the Son nor the Holy Spirit; the Son is neither the Father nor the Holy Spirit; the Holy Spirit is neither the Father nor the Son. But the Father is the Father uniquely; the Son is the Son uniquely; and the Holy Spirit is the Holy Spirit uniquely. All three have the same eternity, the same immutability, the same majesty, and the same power” (On Christian Doctrine, transl. By D. W. Robertson, Jr. [Indianapolis: Bobbs-Merrill, 1958, p. 10]).
(3) Throughout the course of church history, people have asserted that this concept of God is incoherent and logically contradictory. The doctrine of the Trinity, they argue, is irrational, hardly worthy of intelligent belief. As a result, certain heretical concepts of the Godhead have emerged, the two most notable of which are variants of what was known as Monarchianism (also known as Sabellianism after one of their leaders, Sabellius [early 3rd century]). In accordance with their name (monarchy = single principle, Gk.), the monarchians stressed divine unity to the exclusion of any personal distinctions in the Godhead. Some monarchians embraced Dynamic Monarchianism, or more popularly as Adoptionism.
Dynamic Monarchianism conceives of Jesus prior to his baptism as wholly human (the natural born son of Joseph and Mary). As a reward for his exceptional moral virtue, Jesus was adopted as God’s Son and empowered by the Spirit through which he subsequently performed his miracles. Jesus was “divine” not because of any equality in essence with the Father but by virtue of a received power (dunamis). His “divinity”, therefore, is functional or ethical, not ontological.
(4) The other option for some monarchians is known as Modalism. Modalistic Monarchianism believed in both the unity of the Godhead and the deity of Christ. The only viable way to maintain both, so they argued, was to identify the Son (and the Spirit) with the Father. There is only one God who, depending on the circumstances, need, and work in which he is engaged, will variously manifest himself either as Father or Son or Spirit. These names do not stand for eternally distinct persons in the Godhead but were simply different functional expressions for the same God. Jesus is one of several modes or phases or roles whereby the one God reveals himself. Thus “Father, Son and Spirit are distinctions that pertain to God in relation to us. The modalists could affirm the economic trinity (a threefoldness in God in relation to the world) but not the ontological or essential trinity (a threefoldness in the inner being of God)” (Bloesch, God the Almighty, 172).
(5) Although the concept of the Trinity is not explicit in the OT, there are texts in the OT that may allude to the idea of plurality in the Godhead. The standard word for God is elohim (plural). Often a plural verb is used with elohim. See Gen. 20:13; 35:7; 2 Sam. 7:23. There are also texts where plural pronouns are used of God. See Gen. 1:26; 3:22; 11:7; Isa. 6:8. A few OT texts appear to speak of Yahweh having a “son”. See Prov. 30 and Psalm 2. Also relevant are texts that refer to the Messiah. See Isa. 9:6-7; Jer. 32:5-6; Micah 5:2. There are numerous texts which speak about the “Spirit” of God. See Gen. 1:1-2; 6:3; Exod. 31:2-3; Num. 24:2; 27:18; Ps. 51; 139:7. These are but a few of the countless texts mentioning the Spirit. There are a few passages where either the name of God or the concept of deity is applied to more than one person. See Isa. 48:16; 61:1; 63:7-14; Haggai 2:4-7. Continue reading
