Trinity Monotheism

we are monotheists and believe in one God only, and this belief is explained from the Old Testament (the Ten Commandments, Isaiah) and from the New Testament (James).
The speaker explains with logical reasons why polytheism is unacceptable (in terms of authority, creation, power, and judgment).
He clarifies that the Trinity does not negate unity and unity does not negate the Trinity: the Trinity expresses the detailing of the divine essence within one God.
He presents that the Son is the “Logos” or the rational Word and the mind that speaks and God’s wisdom, and through Him the Father created the world — thus the Son is the personification of wisdom and knowledge, begotten of the divine essence eternally and not begotten in time.
The Holy Spirit is the Spirit of God who gives life and quickens creation (Psalm 104) — there is no separation between the persons, but one being with three persons.
It is emphasized that the pagan deities’ triads and human triads (husband, wife, and son) are unsuitable analogies for the Christian Trinity because they involve temporal, gender, and bodily differences.
The speaker answers heresies like Arius and Macedonius by stating that the Son and the Spirit are not created because God’s mind, life, and wisdom have existed from eternity.
