Let's take this ONE at a time
you said, the Lord Jesus, "HE never said Elohim is one person." well let's see then. Matthew 19:3 "The Pharisees also came unto him, tempting him, and saying unto him, Is it lawful for a man to put away his wife for every cause?" Matthew 19:4 "And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female," and the "he" here is God. this is confirmed by our brother Mark who recorded the same conversation in his Gospel. Mark 10:6 "But from the beginning of the creation God made them male and female." so, the "he" in Matthews 19:4 is God.
SECOND, YOU SAID, "HE did say that there are THREE Persons who equate to Echad Elohim". BOOK CHAPTER AND VERSE PLEASE.
