The Council of Nicaea and the three others - a knol by Zia Shah

The best way to understand the doctrine of 'Trinity' is to study its historical evolution. It took four Ecumenical Councils from year 325 CE till 451 CE, spread over more than 100 years and 450 years after Jesus Christ was put on the cross, for the doctrine to arrive in what is its current form.

Contrast all this to the simplicity and beauty of the Muslim creed, "There is no God but Allah!"

No wonder, it has always amazed Muslims, why the Trinitarian Christians do not opt for something better. We extend a cordial invitation to all the Christian brethren in the words of the Holy Quran, "Say, ‘O People of the Book! come to a word equal between us and you — that we worship none but Allah, and that we associate no partner with Him, and that some of us take not others for Lords besides Allah.’ But if they turn away, then say, ‘Bear witness that we have submitted to God.’ " (Al Quran 3:65)
