Tertullian

“ Groundless, therefore, and inconsiderate is the offence of the many [5] who are scandalized by the very fact that heresies prevail to such a degree. How great (might their offence have been) if they had not existed. [6] When it has been determined that a thing must by all means be, it receives the (final) cause for which it has its being. This secures the power through which it exists, in such a way that it is impossible for it not to have existence. ”
