The fundamental problem with the Trinity
Several people have already attempted to provide a comprehensible explanation of the dogma of the Trinity. However, each of these attempts reveals the same fundamental problem: the incorrect definition of the term GOD. Trinitarians define the word GOD not as a "person", but as an "essence"; that is, as the substance or nature of a person. According to John 4,24, GOD is Spirit. Furthermore, a distinction is made between three "persons" or "hypostases," i.e., three independently existing and acting individuals called "Father," "Son," and "Holy Spirit," who share the same divine nature. According to the doctrine of the Trinity, GOD is Spirit, consisting of three persons. From this theory arises the conclusion that Jesus is GOD because he was born of the same divine substance (= Spirit) from which GOD the Father also exists. By declaring GOD to be a "substance," one attempts to avoid the appearance of three gods. Abraham, Isaac, and Jacob were also three persons, composed of the same human nature or substance. Yet they were three human beings and not "one human being."
In truth, however, GOD is not an "entity," "nature," or "substance," but a title who declares someone to be the Creator, Supreme Ruler, and Judge. This unique Creator, Ruler and Judge is Yahweh. Jesus neither prayed to a substance, nor was he raised from a substance, nor did he sit at the right hand of a substance. Wherever Yahweh is mentioned, it refers to a specific "person." This specific "person" has a spiritual nature/substance. Yet, GOD speaks and acts as a "person" and not as a nature or substance. When it is said that GOD is One, this means this one specific "person" and no other. There is always only one throne in heaven on which one person sits (2nd Chronicles 18,18 / Job 1,6-12 / Isaiah 6,1 / Revelation 4,2). In other words, GOD as a "person" is One (not His nature). Therefore, only the Father is called GOD. Jesus is the Son of GOD / the Son of the Most High, i.e., the Son of this unique "person", while the Holy Spirit is called the Spirit of GOD / the Power of the Most High, i.e., the Spirit of this unique "person". For the same reason, the New Testament alone mentions GOD the Father in over 500 places, while the terms "GOD the Son" or "GOD the Spirit", which Trinitarians frequently use to denote the divinity of Jesus and the Holy Spirit as the second and third person respectively, are nowhere to be found in the entire Bible. Jesus is not the Son of a "devine nature or substance". The same applies to the Holy Spirit. In that respect Trinity inevitably means that there are three divine persons and thus three Gods. While they possess the same essence or nature, they can never be "one" GOD (in the sense of "one" individual).
Wherever the words God or gods are used in connection with pagan deities such as Artemis, Asherah, Astarte, Baal, Dagon, Diana, Milcom, Moloch, etc., they also refer to (in this case, nonexistent) "persons." When it is said that Moses is to be God for Aaron, this refers to his authority and not to Moses' nature (Exodus 4,16). The plural word gods also describes multiple "persons" and not multiple divine substances. The judges in the Old Testament were called gods because of their authority to judge the people vicariously in the name of the one GOD. This title has nothing to do with their nature. Each of these "gods" was a person, not a nature. Nor were multiple judges referred to as "one god," as would be required according to the Trinitarian definition. Being born of GOD or begotten by GOD (John 3,5-7) does not mean that someone is GOD or consists of the same divine substance as the Father. It means having the same mind/attitude as GOD. This can refer to both humans and angels. Those who obey GOD's commandments are descended from GOD (1st John 3,9) and are one (= of one mind) or one spirit (= of one spirit) with Him (John 10,33 / John 17,22 / Romans 8,9 / 1st Corinthians 6,17). Those who behave according to the flesh are descended (in the spiritual sense) from the devil (John 8,44 / 1st John 3,8).
GOD is not a substance, but a unique "person". This unique GOD is the Father in heaven. Based on the biblical definition of the term GOD, the doctrine of the Trinity can no longer be maintained in any way. As soon as one sees through this fundamental problem, the entire construct collapses. Furthermore, it is not understandable why GOD only indirectly hints at this supposedly most important truth of all in His Word, without a single confession being found which expresses in clear words that GOD exists in three persons, or that Father, Son and Holy Spirit are ONE GOD. All the central truths Christians believe in are unequivocally and comprehensively attested to in the New Testament (see crucifixion, resurrection, second coming, judgment, etc.). They do not need to be derived by linking individual verses that have been interpreted in a particular way, as is the case with the Trinity. Thus, the Trinity remains a human doctrine without a biblical foundation.
