If Jesus is not God, as John asserts and Jesus himself declares, and if he is not “my Lord and my God” as Thomas exclaims, then we have no hope. We have no gospel. Jesus is able to die in our place and reconcile us to the Father precisely because he is the divine Son of God, worthy to atone for the sins of all who would believe in him.
I usually don’t care to debate the theological opinions I hear on the radio. This is mostly because I believe Christian radio hosts are simply trying to love Jesus, love people, and do some encouraging things in the world. Furthermore, they do not seem to offer their opinions as though they believed they were the official teachers of the church universal.
Every now and then, however, someone says something that causes me to say, “No!” In my head, this is usually followed by a little bit of debate with whoever said what they said. In this hypothetical interaction, I often attempt to offer a bit winsome correction. To be honest, though, this is simply an exercise that helps me get my own head around why I think what I just heard is out of theological bounds.
The other day I was driving down the road and listening to a Christian radio station somewhere in Wisconsin. I do not remember what song had just played and, honestly, I do not recall much of what was going on. However, at one point the host said something along these lines:
“When we spend time with Jesus, by proxy we meet with God.”
When I heard that, I paused. I immediately knew something was off. But I wanted to be sure, so (at the next stop), I looked up the dictionary definition of proxy to see if it meant what I thought it meant. Here are the definitions of proxy via Merriam-Webster.
First, Webster provides the “essential meaning.”

A person who is given the power and authority to do something (such as vote) for someone else;
Power or authority that is given to allow a person to act for someone else.

Then, a fuller meaning is provided. The problematic language within the “essential meaning” and the “fuller meaning” is simply that a “proxy” acts as a “substitute…for another.” The idea of being a proxy is that the proxy represents and acts for someone else, for someone they are not. For instance, imagine if it were legal to allow your spouse to vote in your place during an election. I might give my wife the right to cast my vote if I’m unable to do so due to sickness, travel, or any other unforeseen circumstance. She acts on my behalf yet she is not me. Or, perhaps, imagine I have given power of attorney to her so that she can sign a document for me. She again acts on my behalf but she, again, is not me. We are not the same person.
If that is the meaning of proxy, then the host of the radio show has said in essence that when you meet with Jesus, you meet with God via someone who acts on God’s behalf but is not God himself. At least this is the implication of the words, even if this was not the intent. He did not say that when you meet with Jesus, you meet with the Father via proxy. There is perhaps a way we could nuance that to make it work, since the Son is not the Father, though they are one in essence. But, even there, the Son and the Father, along with the Spirit, are without division. To meet with the Son is to be with the Father and the Spirit. However we might have parsed out that idea is beside the point. The host said that when you meet with Jesus, you meet with “God via proxy.” That does not work, because to meet with Jesus is to meet with the God of the Cosmos.
The Bible is abundantly clear on the identity of Jesus Christ. He is no mere mortal. Jesus is God of very God, while also being fully human. When we talk of Jesus, we speak of the one in whom perfect deity and complete humanity are joined together without mixture or confusion.
The Gospel of John paints the picture as clear as any portion of the Bible. As soon as John opens his Gospel, the deity of Jesus flies off the page.
In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it. (John 1:1-5)
In the context of John, the Word is a reference to Jesus (John 1:14). John opens by pointing to the creation account in Genesis, letting the reader know that this Jesus, though recently born of a woman, was there when the world was created. He was with God at the start and, in fact, “was God.” Being God, he is the agent of creation and had life in himself. He was, then, the a se Word (from where we get the idea of aseity).
