A Brief Note on S 4:171

S 4:171 People of the Book, do not exceed in your religion nor say about Allah but the truth. The Messiah Isa Son Of Maryam is only Allah’s messenger and his word which he threw to Maryam and spirit from him. So believe in Allah and his messengers and do not say Three. Cease; it is better for you. Allah is only one god. Praise be to him that he should have a child! His is what is in the skies and what is on the Earth. And Allah was sufficient as an agent.

The People of the Book is used of the Christians and the JEWS. See my post: On the Term ‘People of the Book’ How many messengers might Allah have at any one time? One? If one then surely Isa would be that one. It doesn't say 'WAS Allah's messenger' nor does it say 'ONE OF Allah's messengerS'. Were the Arabian Jews Trinitarians? Isa is ONLY Allah's word and spirit from it? "[D]o not say Three. Cease; it is better for you." Is it GOOD if you say it but BETTER if you don't? "Praise be to him"? But isn't Allah supposed to be speaking? "Allah was sufficient as an AGENT"? See my post: Allah WAS sufficient?and Agent Allah
