An Overview Of The Doctrine Of The Trinity P3: God the Father's eternal act of begetting and God the Son being eternally begotten.

Introduction:

    To review, we covered the first pair of truths that help us in beginning a study of the doctrine of the Trinity: God is one in being and a plurality in Personhood. Readers who want to review the last post may click on the link here Growing Christian Resources: An Overview Of The Doctrine Of The Trinity P2: God's Oneness of Being and Plurality of Personhood. I referred to this pairing as two pillars upon which we begin to understand the Biblical revelation of the Triune God. In this post we will introduce a second pair of truths that focus attention upon the Person of the Father and the Person of the Son. 

    In the Triune God we often see several pairs of truths associated with the four main ones we're focusing upon in these posts. One important pairing to keep in mind is how the Father and Son are united in essence while distinguished from one another. Another important pairing of truths aside from the four main ones involves the Holy Spirit's union to the Father and the Son while He relates to them and they to Him.1 I mention these two other pairings of truths so that we can keep in mind that first major pairing we looked at last post (God is one in being and plural in Person). 

The main passages used to support the Father begetting the Son and the Son being begotten of the Father.

   To remind ourselves again, those who argue for the eternal generation (i.e. "begottenness" of the Son) teach that the Son of God is "eternally generated", meaning that that Father eternally communicates to Him the entire Divine nature, point for point, with all perfections. For example, John MacArthur in his book "Essential Christian Doctrine", lists Scriptural verses that feature some main Divine attributes shared between the Father, the Son, and the Holy Spirit. 

           Father           Son     Holy Spirit

Eternal: Deut 33:27            Jn 1:1       Heb 9:14

Omnipotent: Mt 19:26         Re 1:8       Lk 1:35

Omniscient: Lk 16:15          Jn 16:30   1 Cor 2:10-11

Omnipresent: 1 kgs 8:27      Mt 28:20   Ps 139:7

Immutable:   Mal 3:6           Heb 1:10-12  Heb 9:14

Loving:        1 John 4:8       Eph 5:2      Rom 15:30

Holy:           Lev 11:45        Heb 7:26-27  Ro 1:4

Truth:          Jn 3:33           Jn 14:6         Jn 15:26

    What this list shows us is, for example, that God is not three eternals, three omnipotents, three omnisciences, and so forth; rather He is One in each of these Perfections as expressed in the Three Persons. Jesus spoke of He and the Father as "One" in John 10:30 in reference to "being"; yet clearly distinguishing between Himself and the Father (i.e. "I and the Father"). The Athanasian Creed summarizes this point as follows:

"What quality the Father has, the Son has, and the Holy Spirit has. The Father is uncreated, the Son is uncreated,         the Holy Spirit is uncreated. The Father is immeasurable, the Son is immeasurable, the Holy Spirit is immeasurable. The Father is eternal,       the Son is eternal, the Holy Spirit is eternal. And yet there are not three eternal beings; there is but one eternal being. So too there are not three uncreated or immeasurable beings; there is but one uncreated and immeasurable being."

     Also, the distinguishing characteristic of the Son, "begottenness", is conveyed by the Father to Him, with the Father Himself being the unbegotten Person, hence distinguishing Him in identity from the co-equal and co-eternal Son. 

    There are proof texts that theologians in favor of this doctrine appeal as direct evidence for the doctrine, and then a handful of passages that theologians would say are indirect proof-texts.

Direct proof-texts for the eternal generation of the Son from the Father

John 1:14 "And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth."

John 1:18 "No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him."

John 3:16 “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life."

John 3:18 "He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God."

1 John 4:19 "By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him."

    In addition to these five Johannine proof texts, a few others that convey the teaching of the eternal generation of the Son are used. In Proverbs 8:24-25, Wisdom is personified and described as "brought forth" from God before creation of anything else: 

“When there were no depths I was brought forth, when there were no springs abounding with water. 25 “Before the mountains were settled, Before the hills I was brought forth." 3

Indirect Proof Texts

    Although the following other passages do not use the term "only-begotten", the idea of the Son being eternally generated by the Father is resident in their various phrases. Colossians 1:16-17 "For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things have been created through Him and for Him. 17 He is before all things, and in Him all things hold together. 18 He is also head of the body, the church; and He is the beginning, the firstborn from the dead, so that He Himself will come to have first place in everything." I've highlighted four phrases in Paul's words here in Colossians. 

    The first three bolded phrases portray the Son as responsible for creation, rather than being created, as some groups like the Jehovah Witnesses would advocate. The term "firstborn" is a Greek noun that refers to inheritance more so than just mere birth-order. The Son of God was promised in eternity, by the Father, that He would inherit all of creation before it was made (compare Psalm 2:8; 82:8).

    There are other indirect proof texts we could offer, but for sake of space let me submit Psalm 2:7 "I will surely tell of the decree of the Lord: He said to Me, ‘You are My Son, Today I have begotten You." The word "today" in context is not referring to there at that moment. Sometimes in the Bible, the term "day" can refer to an indeterminate period of time, or even eternity itself.

The importance of the Son being begotten of the Father

    I'll lay out three major points about the Son being begotten of the Father as a way to arrive at its meaning as found in the Bible.

1. Eternal generation (and thus "begotten") explains why the Son is eternal. 

    First, those who argue for the eternal generation (or begottennness) of the Son teach that Father eternally communicates to Him the entire Divine nature (or at least His identity as the Son). According to theologian Matthew Barrett, the Divine essence is shared without division from The Father to The Son: 

"The concept takes us to the very heart of what it means for the Son to be a Son. He is eternally from the Father, which is why He is called Son. To be more specific, from all eternity, the Father communicates the one, simple, undivided divine essence to the Son."2

    The eighteenth century Baptist Theologian John Gill explains eternal generation a little differently as the Father communicating the Son's identity, whilst both share in the common essence:

"It is better to say, that they are self
existent, and exist together in the same undivided essence; and jointly, equally, and as early one as the other, possess the same nature’. Thus, there is not one person who, in the personal ordering of the Trinity, communicates the essence to the others. There are simply three, who relate personally to one another in the essence, with each person possessing the essence of himself." 3

 

   Both explanations of eternal generation fall within the pale of Bible-believing orthodoxy and views that draw from the Nicene Creed's confession of the Son being "begotten, not made". Eternal generation or begetting of the Son firstly explains why the Son is eternal. Notice a second general observation.

2. Eternal generation explains why the Son is the Son, and why the Father is the Father. 

    Then secondly, the distinguishing characteristic that defines the Son as "the Son" is in how the Father begets Him or what theologians call "filiates". Filiation conveys to the Son His identity as the Son, as noted already in my quotation of John Gill.

3. The Son being begotten has relevance in modern evangelism

    I recall years ago a group of Jehovah Witnesses handing out pamphlets advertising a local conference at their "Kingdom Hall" meeting place: 

"Come hear about how Jesus Christ is the Savior of the World".

    I pointed out to them that according to their theology, there is no way Jesus Christ could be Savior of the World. I took them to the above passages I cited. I concluded that they either had to admit their theology was in error, or stop proclaiming that Jesus Christ is Savior of the World. They of course would not do either. 

    Nevertheless, the phrase "begotten, not made" safeguards the central affirmation of the Gospel that the Apostle Peter affirms in Acts 10:38 "Jesus Christ is LORD". Or again, Paul writes in Romans 10:9 "If you will confess with your mouth Jesus is LORD, and believe in your heart that God raised Him from the dead, you will be saved."

    Both Scriptures cited above use the Divine title "LORD" or "Jehovah/Yahweh" to show the Son's equality with the Father, as well as to demonstrate that He is able to save sinners just as much as the Father, since He Himself is God. 

Endnotes:

1. Theologians call the relations between the Father, Son, and Spirit "eternal relations of origin."
