The Trinity is supported by the Hebrew Tanakh

Before proceeding with an opening argument, I will outline the definition of “Trinity”: n., pl. -ties for 2,4. 1. the union of three persons (Father, Son, and Holy Ghost) in one Godhead, or the threefold personality of the one Divine Being. 2. Trinity Sunday. 3. (l.c.) a group of three; triad. 4. (l.c.) the state of being threefold or triple. 1 : the unity of Father, Son, and Holy Spirit as three persons in one Godhead according to Christian dogma. 2 not capitalized : a group of three closely related persons or things. 3 : the Sunday after Whitsunday observed as a feast in honor of the Trinity. Origin of TRINITY Middle English trinite, from Anglo-French trinité, from Late Latin trinitat-, trinitas state of being threefold, from Latin trinus. First Known Use: 13th century. Opening Argument While “the Trinity” has largely been endorsed by some Christian sects (namely Catholicism) it has never been practiced or accepted within the religion of Judaism; primarily for the fact that no such thing is indicated within the Tanakh. In fact, historically the Christian doctrine of “the Trinity” has been met with opposition from Jews, particularly when possible reference to the Tanakh has been made. In Jewish law, worship of the three-part deity is considered idolatry. Even Jews that have held a belief in Christ, such as the early Judeo-Christian sect of the Ebonites, protested against it. History books provide us with the evidence that the belief of “Tri-unity” came from the Athinasian creed. It was published and introduced around 300 years after the religious leader of Christianity (Christ) died. The creed was used when the Romans made the transition from being Pagans to Christians. Here is a quote from it: “The Catholic faith is this, that we worship one G-d in Trinity and Trinity in unity. Neither confounding the Persons, nor dividing the substance. For there is one person of the father another of the son and another of the holy ghost. But the G-dhead of the father, of the son, and of the holy ghost is all in one, the glory equal to the majesty co-eternal”. This particular quote is explicit in its lack of reference to the Tanakh and individual belief of the Trinity. A belief, that is not shared by Jews, and is even questioned by some Christians. If there was any suggestion of a Trinity within the Tanakh, like other things, it would’ve been recognized by the Jewish people themselves; but no such thing has been observed. No where in the Tanakh is a word reminscent of Trinity, and no where is it stated that G-d, is made of three seperate natures. Judaism strongly upholds the belief that G-d is one and Indivisble; that there can be no plurality or division on his part. The fact that Jews have also not received “the son”, who Christians consider to be Jesus, should also be taken into account. One thing that the Trinity does imply is that “the son” is on equal standing with G-d, which again is heavily at odds with Jewish belief. Context of “Elohim” In round two you have highlighted the “Elohim” argument that is often used in defense of a Tanakh and Trinity connection. The fact is, however, that the variable context of the term “Elohim” and its applications are not considered. For example, individual men can be called Elohim—Moses (Parshah Shemot) 4:16; 7:1), a judge (Parshah Shemot 22:8, 9, 28), and the Davidic. King (Tehillim 45:6). The plurality of the word is rather a description for “greatness” and “fullness” or “magnification”. It is not implied as a reference to a triune G-dhead. The use of plural terms in replacement for singular is also not uncommon within the Hebrew language. In addition, the singular term for G-d “Eloah” is also used in the Tanakh. Context of the “Shema” As with “Elohim” it’s occasionally noted that the use of the term “Echad” in the Tankah is evidence of there being a Triune G-d. Indeed “Echad” does mean when two or more people join together to form a “oneness”; such as when a man and woman get married and become “one flesh” (Genesis 2:24). The Hebrew word for compound unity and togetherness, which is what the Trinity entails, is in fact “Yachid”-not Echad. An example of Echad meaning a singular term or being used as an inference for a single one can be found in other passanges in the Tanakh. (Yesha’yahu) 51:2) “Look to Abraham your father…when he was echad (one single man) I called him…and multiplied him”. (Yechezkel 33:24) “Abraham was Echad (only one man), yet he possessed the land; so to us who are money the land has been given”. Echad can also translate as the “first”, the “same” and “unique”. Such as in (2 Shmuel 7:23) “It will be a unique day (Yom Echad) which is known to G-d.
