1 Thess 5:23 is known as a proof text for tripartism and can easily be understood as Paul doing a typically Hebraic practice of repeating synonyms for emphasis (just like we even say, “first and foremost,” or, “null and void”). Elsewhere its clear Paul uses “soul” and “spirit” interchangeably.
Scripture says we are created in God’s image; it never says human beings have a trinity, “Father, Son, and Holy Spirit” nature.
But of course this is an issue which orthodox Christians differ. If you want to agree with the non-Christian Scientologist cult on this, go ahead.
Like I said,”A minority view amidst Christians is we are 3 parts, body, soul, and spirit.”
There are dichotomous and trichotomous views of man’s anthropology.
The Old Testament calls on the the nephesh as being God breathed life in the man. Plants do not have nephesh, but animals do have nephesh and part of the reason why the blood sacrifice of the animal was acceptable to God, while Cain’s plant sacrifice was lesser.
The NT refers to the soul as being composed of the heart and the mind.
The sacrifice of Christ on the Cross, was in reference to His soul being given.
Upon faith alone iin Christ alone, God the Holy Spirit regenerates the human spirit, distinct from the mind or heart.
I would have to say that they agree with most Christians.
Please show me where Paul has used spirit and soul interchangeable. If you look at the Greek words they are different and if Paul wrote the letters then when he used soul that is what he meant and when he used spirit that is what he meant.
