The term “tamim” is a Biblical Hebrew word, an adjective form of the verb tamam (be complete) and the noun tom (completeness). Tamim indicates a condition of something being complete, perfect, accomplished, intact, healthy, whole, entire, blameless, integral, or sound (cf. Genesis 17:1; Exodus 12:5; Psalm 101:2; Proverbs 11:20; Ezekiel 15:5; Amos 5:10). The meaning of tamim is based ultimately on it being part of Elohim’s (God’s) own complete nature (cf. 2 Samuel 22:31).
We believe that wholeness, or completeness, as felt and experienced in earthly life, is the deep inner desire of every reasonable human being, regardless of one’s ability to explain it. However, most people in daily life do not desire or think in terms of a Biblical approach to experiencing completeness.
In “Tamim Messianic Judaism,” the term “Messianic” is used to refer to our spiritual faith and practice revolving around belief in the Biblically promised Messiah-King and Savior of the world. A sincere belief in such an ultimate Messiah is found in the Tanakh (Old Testament) (Isaiah 53; Jeremiah 23:5-6), and throughout the Brit Khadashah (New Testament) (John 1:41; Acts 26:23). The predicted Messiah has two comings, or arrivals, into earthly life: the first time to suffer, the second to reign as King.
In “Tamim Messianic Judaism,” the term “Judaism” refers to the ancient Judaic roots of Christianity, along with possible modern worship applications. There is nothing wrong with using the sincere term “Christian” as a label of faith (1 Peter 4:16); nor is it wrong for sincere believers in Yeshua (Jesus) to use the label “Messianic Jews” to refer to themselves. The New Testament Apostles held the view and taught that genuine believers in Yeshua (Jesus) were in meaningful spiritual relationship with YHVH Elohim (LORD God), and this relationship made the believers spiritually Jewish (cf. Ephesians 2:8-22). The New Testament expresses that being spiritually Jewish through faith in Yeshua (Jesus) as Messiah is necessary for vital relationship with Elohim (God) (John 4:22-26).
Therefore we choose to call our approach Tamim Messianic Judaism. The name is an identifier; it is not a criticism against other genuine Messianic Jews or Christians who believe in the Messianic supremacy of Yeshua (Jesus).
