Tertullian

“ Will some separate order of monogamists have to be instituted, from which to make selection for the clerical body? (No) ; but when we are extolling and inflating ourselves in opposition to the clergy, then “we are all one:” then “we are all priests, because He hath made us priests to (His) God and Father.” ”

“ For that which he prescribes to certain (individuals) he does not prescribe to all.” Does it then follow, too, that to bishops alone he does not prescribe what he does enjoin upon all; if what he does prescribe to bishops he does not enjoin upon all? or is it therefore to all because to bishops? and therefore to bishops because to all? For whence is it that the bishops and clergy come? Is it not from all? If all are not bound to monogamy, whence are monogamists (to be taken) into the clerical rank? ”
