How is it impossible for God to have Three Divine Persons that are One in Essence? If He’s God why should we question how He Manifests Himself and apply a human definition of ‘oneness’ upon Him and say the Trinity is impossible. How do Muslims feel about this?
Firstly, let me say, Muslims worship God. They adore and believe in the same God as Christians, Jews, and all those who worship the Creator, for God is God, the one God, the Lord, the Almighty. (Catechism of the Catholic Church 841)
Secondly, Muslims do not impose a human definition of oneness upon God. They merely believe in God, the one God. They do not believe in the Holy Trinity, as we Catholics do, because they are taught that there is no Trinity, and the Qu’ran teaches this too. (Qur’an 4:171)
Thirdly, we must live by the Great Commandment, namely, Love. Yes, we must live in love for each other, for Jews, for Muslims, for Buddhists, for Satanists, for atheists, for agnostics, and for the enemies of the Church. If we say we love God but hate others, we are liars. (1 John 4, 20)
