“For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.” I Jn. 5:7
The word of God can often be logical, but sometimes it isn’t. Sometimes you can strengthen a doctrine by adding logic and sometimes you can’t. There was a man I got to know over 30 years ago who belonged to a church that denied the triune God. Their doctrine is usually referred to as Jesus only or the oneness doctrine. Their church affiliation is usually labeled as apostolic or United Pentecostal. Anyway, this man tried to use logic on me to try to convince me that Jesus and the Father are one. So he asked me if I am a son, and of course I confirmed that I was. Then he asked me if I was a father, and since I had three sons, I confirmed that as well. So he said the same thing with the Father and the Son, they are just one person. Well, being young in the Lord I was still not persuaded by this argument. Let’s use his point of logic for a minute. I am a son, because I have a father. I am a father because I have a son. It takes three people for this to happen, my dad, me and my first born son. This man’s logic actually supports the trinity more than it does oneness. Yes, there are three that bear witness in heaven.
