YHVH God says though Moses to the children of Israel, “Love your neighbor as yourself”. (Lev 19:18)
Golden Rules
Judaism – Talmud, Shabbat 31a
“What is hateful to you, do not to your fellow man. This is the law: all the rest is commentary.”
Christianity – Matthew 7:12 (New Testament)
“Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.”
Islam – Number 13 of Imam “Al-Nawawi’s Forty Hadiths”.
“None of you [truly] believes until he wishes for his brother (i.e., fellow Muslim) what he wishes for himself.”
God and Christ/Messiah (Prophet, King, Priest)
Judaism says that YHVH God is a Father, and there is a Messiah, but that Jesus is not God’s unique and only begotten Son, nor is He the Messiah and King of Israel.
Islam says that God is not a Father, and so He has no Son (or any children), and that Mohammed is the Prophet of their God.
Christianity says that Jesus/Yeshua is the Christ/Messiah, the Son of the Living God. (Mt 16:16; 1Jn 2:22-23)
