"I offer no sacrifice save to the One true God."
~ Maximus, martyr, saint, about A.D. 250, in answer to the demand of the civil authorities for sacrifice to the pagan gods; a test in common use as belief in a single Godhead was known to be definitive in the early Christian community; thus any Christian might be called on to seal with his blood his faith in the One God.
