In the last blog, I talked about how we as Christians are united. I also mentioned there is a line, a doctrinal line, between orthodox Christianity and cults. One of the essential doctrines that set apart Christianity from cults is the Trinity, so I thought I’d look at there here.
Definition
The trinity doctrine is described like this: In the nature of the one true God there are three divine Persons, God the Father, God the Son, and God the Holy Spirit. The three Persons are the one true God. But, where do we find this in Scripture? Here are some passages:
The Father is God: Gal. 1:1
The Son is God: Heb 1:8
The Holy Spirit is God: Acts 5:3-4
Yet there is only one God: Isa. 44:6; Acts 2:24.
Three persons are called God, yet there is only one God. Therefore the three Persons are the one God. It’s defined as simply as that.
Within the trinity, the Son and Holy Spirit are submissive to the Father. They are not inferior in any way except positionally. Their submission is voluntary. We’ll look at that more when we look at the deity of Christ in a future post.
Some History
Throughout church history there have been disagreements on this doctrine. Mostly the arguments centered around the deity of Christ. For now, just understand the orthodox (standard) belief was that Jesus is God, equal to the Father.
The trinity has always been understood within Christianity. Look at how early the trinity appears in Christian writings. Polycarp, the Bishop of Smyrna, a disciple and coworker with the Apostle John for years, wrote this: ” I have collected these things, when they had almost faded away through the lapse of time, that the Lord Jesus Christ may also gather me along with His elect into His heavenly kingdom, to whom, with the Father and the Holy Spirit, be glory for ever and ever. Amen.
So, not only does the trinity appear in Scripture but also in the writings of the early church.
There have been several misunderstandings concerning the trinity and how it works however.
Modalism: This idea was championed by a guy named Sabellius who died around 215 a.d. The belief didn’t die with him, though. It continued for several centuries and still appears in sects like the United Pentecostal Church. This is the belief that God is just one Person who wears three hats. There are two major forms of this. The first is dynamic modalism where one believes God acted as the Father in the Old Testament times, as the Son when Jesus walked the earth, and as the Holy Spirit today. Static modalism, the second major form, says God acts as the Father in His creation, as the Son in redemption, and as the Holy Spirit in our sanctification. This doctrine was attractive to early believers since it solved the problem of three Persons but one God.
Tritheism: This is the belief that the trinity is actually three separate gods. It was briefly the teaching of Dionysius the bishop of Alexandria (d. 264 a.d.) trying to disprove the Sabellian heresy. The church pointed out his error. He then admitted his error and returned to orthodoxy. Mormons believe a form of Tritheism.
Arianism: This doctrine is named after Arius of Alexandria (c. 250-336 a.d.). Arianism is the teaching which brought about the Nicene Council (325 a.d.) which issued the Nicene Creed.
Arianism is the belief that only the Father is God. The Son is His first and greatest creation through which He created the universe. Normally, very little attention is paid to the Holy Spirit, but some Arians believe He is just God’s force. Many in the early Eastern church believed God could not be involved with matter. This solved that problem by teaching it was not God but His creation (Jesus) which created matter. Jehovah’s Witnesses are modern day Arians.
The church’s orthodox stand on the trinity was not officially and fully settled until the Council of Nicaea in 325 a.d. though, as I said above, it was believed much earlier. Brave men stood strongly and boldly against the misinterpretations of this doctrine. Athanasius (300-373) Bishop of Alexandria, spent most of his life combating Arianism. Arianism was a huge threat to orthodox theology for several centuries. Even at age 25, Athanasius was a major player at the Council of Nicaea but suffered exile five times throughout his life for defending the Nicene Creed and the trinity doctrine it presented.
So, while the trinity may be a little hard to understand, it is clear from Scripture that God exists in three divine Persons, Father, Son, and Holy Spirit yet is one holy and everlasting God.
Why is this important?
Knowing God better is always important, and understanding Who and What He is adds to that. Also, God is triune and chooses to exist that way. He is a God Who is communal. Maybe that’s why He made us. I’m sure that’s why He encourages us to gather in families, friends, and churches. The more we understand God, the easier it will be to relate to Him.
