As Freemasonry embraces all men of different religions, it could cause disharmony if we specifically referred to God. For this reason, a number of variations are used such as 'the Great Architect'.
The names used for the Supreme Being enable men of different faiths to join in prayer without the terms of the prayer causing dissension among them. There is no separate Masonic god, and a Freemason's god remains the God of the religion he professes. Freemasons meet in common respect for the Supreme Being, and it is no part of Freemasonry to attempt to join religions together.
