They became deeply divided and fragmented over the Trinity and union, in ways no rational person would accept. No scriptural evidence supports this apart from ambiguous expressions in the Gospel and earlier scriptures, which are explained by unambiguous passages in those same scriptures. These all affirm that the Messiah is Allah’s servant, worshipping Him alone, praying to Him, and humbly beseeching Him.

The foundation of religion is faith in Allah and His Messenger, as the Seal of the Prophets and Messengers said:

“I have been commanded to fight the people until they testify that none has the right to be worshipped except Allah and that Muhammad is the Messenger of Allah.”

He also said:

“Do not praise me excessively as the Christians praised Jesus son of Mary. I am only a servant, so call me Allah’s servant and His Messenger.”

Religion thus consists in affirming Allah’s oneness and acknowledging His messengers. This is why the Sabians and polytheists, such as the Brahmins and other deniers of prophethood, associate partners with Allah in their beliefs and worship, and hold corrupt beliefs concerning His messengers.

Those who profess a Trinity in matters of divine oneness and union in matters of messengership have corruption within the very foundation of their religion. This corruption is evident both from the natural disposition with which Allah created humankind and from the scriptures He revealed. This is why the general pattern among their leaders—priests and monks, including patriarchs, metropolitans, and bishops—is that, when one of them becomes learned and discerning, he abandons his religion and becomes a hypocrite before the rulers and common people of his faith
