From Genesis 1:27 "So God created man in his own image, in the image of God he created him, male and female he created them." So what is the image of God?
The image of God would be his communicable attributes: love, goodness, kindness, being creative, the ability to reason, compassion, justice, etc. Although, we do these things imperfectly and to a lesser degree than God.
From Revelation 1:13 "and in the midst of lampstands one like a son of man, clothed with a long robe and with a golden sash around his chest." So Christ looks like human beings albeit infinitely more in splendor. Christ is the Son and the Father also bears his resemblance.
First, this is post-incarnation, post-resurrection with the Son in his glorified body. The Son will likely remain the God-man for eternity. Second, we know that the Son “was in the form of God” but then entered time, coming to earth and being “born in the likeness of men . . . in human form" (Phil 2:6-8).
So, we have the two forms being contrasted, where Jesus’s body is clearly human form. We know that God is spirit (John 4:24), which means the Son would have been only spirit prior to the Incarnation. While there are theophanies in Scripture, there is nothing to suggest that the Father and preincarnate Son actually existed in a form resembling humans.
Now what about the Holy Spirit. There is nowhere in the scripture where the Holy Spirit has the image of the son of man. We have instead from Revelation 4:5 "...and before the throne were burning seven torches of fire, which are the seven spirits of God."
But, why should the Holy Spirit have to be seen as having "the image of the son of man"? Spirit is spirit, not man.
Also, in all of the epistles from Paul to Jude introductory greetings are done in the name of the Father and the Son. No where is the Holy Spirit found.
Not quite true:
1Pe 1:1 Peter, an apostle of Jesus Christ, To those who are elect exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
1Pe 1:2 according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you. (ESV)
Apart from that, the Holy Spirit is certainly found. However, the focus is always on the Father and the Son, as one of the Spirit's main roles is to bring glory to Jesus, who then brings glory to the Father.
Now some of you shall say, well what about Matthew 28:19? This is where it gets tricky for there is a lot of discussion on whether "the Holy Spirit" was added later by the first Nicean Council.
So, at worst, we can neither count it nor discount it. However, as it is, it is consistent with the full revelation of who God is and so is likely original.
And note from Acts 2:1-4 that the apostles were filled with the Holy Spirit after Christ died, where the Holy Spirit appeared like tongues of fire. Again, it did not appear in some human shape laying on hands.
But should that matter? The Holy Spirit is spirit and not human. There is nothing in Scripture to suggest that the Father is in human form or shape. The Holy Spirit also descended on Jesus like a dove, but that doesn’t mean the Holy Spirit is a dove.
The question for you is: who or what is the Holy Spirit?
In John 14:16 Jesus mentions "another Helper," which would mean one similar to him (“Helper"), yet distinct ("another"). It is important that "Helper" or "Comforter" is the Greek
parakeltos, or
Paraclete, which is best translated as "advocate" (see 1 John 2:1). Only persons advocate. Similarly, Rom 8:26 speaks of the Spirit as interceding for us, which, again, is the domain of persons.
Here is a bit of a summary on why the Holy Spirit is a “person”:
Acts: Matt 4:1; Acts 8:39, 16:7,
Speaks: Acts 1:16, 10:19, 11:12, 11:28, 13:2, 15:28; 1 Tim 4:1; Heb 3:7
Can be lied to: Acts 5:3, which is the same as lying to God (5:9)
Bears witness: Rom 8:16; Heb 10:15; 1 John 5:6
Helps, intercedes, and searches: Rom 8:26-27, 1 Cor 2:10
Teaches: Luke 12:12; 1 Cor 2:13
Gives gifts: 1 Cor 12:11; Heb 2:4
Leads: Gal 5:18, Heb 9:8
Can be grieved: Eph 4:30
Can be outraged: Heb 10:29
And on it goes. These are all actions of personal agency.
I believe in Father and Son personally.
Who is the Son?
We have to be clear on what we worship. I take the warning in Revelation 22:18-19 seriously and Paul said we must prove all things. No one has been able to convince me so far about the trinity except to point to the deep mystery of it all requiring some PhD in divinity.
The Trinity is a mystery, but that doesn’t mean it requires a PhD. No one can fully comprehend it—it’s a mystery—but we can understand certain things. The Bible clearly teaches:
1. There was, is, and ever will be only one true God.
2. The Father is not the Son nor the Holy Spirit and neither is the Son the Holy Spirit—three divine persons.
3. The Father is God, the Son is God, and the Holy Spirit is God—coequal, coeternal, consubstantial.
Those are what the doctrine of the Trinity takes into account.
From Matthew 11:30 "For my yoke is easy and my burden is light."
We should keep that in context:
Mat 11:28 Come to me, all who labor and are heavy laden, and I will give you rest.
Mat 11:29 Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls.
Mat 11:30 For my yoke is easy, and my burden is light.” (ESV)
We can see that it doesn't have anything to do with any revelation about the nature of God. It's about finding our rest in Christ. So, we cannot use it to mean that all things in Scripture are easy to understand and anything complex and ultimately incomprehensible cannot be of God, particularly that the infinite God should be able to be fully comprehended by the finite mind. If a person can fully comprehend God, then their god is one of their own making.
