What has Athens to do with Jerusalem? - Tertullian

For the very Church itself is, properly and principally, the Spirit Himself, in whom is the Trinity of the One Divinity—Father, Son, and Holy Spirit. (The Spirit) combines that Church which the Lord has made to consist in “three.” And thus, from that time forward, every number (of persons) who may have combined together into this faith is accounted “a Church,” from the Author and Consecrator (of the Church). And accordingly “the Church,” it is true, will forgive sins: but (it will be) the Church of the Spirit, by means of a spiritual man; not the Church which consists of a number of bishops. For the right and arbitrament is the Lord’s, not the servant’s; God’s Himself, not the priest’s.

Nec alii obest aut prodest alterius religio.

For in the beginning of the world He gave to Adam himself and Eve a law, that they were not to eat of the fruit of the tree planted in the midst of paradise; but that, if they did contrariwise, by death they were to die. Which law had continued enough for them, had it been kept. For in this law given to Adam we recognise in embryo all the precepts which afterwards sprouted forth when given through Moses; that is, Thou shalt love the Lord thy God from thy whole heart and out of thy whole soul; Thou shalt love thy neighbour as thyself; Thou shalt not kill; Thou shalt not commit adultery; Thou shalt not steal; False witness thou shalt not utter; Honour thy father and mother; and, That which is another’s, shalt thou not covet. For the primordial law was given to Adam and Eve in paradise, as the womb of all the precepts of God. In short, if they had loved the Lord their God, they would not have contravened His precept; if they had habitually loved their neighbour—that is, themselves—they would not have believed the persuasion of the serpent, and thus would not have committed murder upon themselves, by falling from immortality, by contravening God’s precept; from theft also they would have abstained, if they had not stealthily tasted of the fruit of the tree, nor had been anxious to skulk beneath a tree to escape the view of the Lord their God; nor would they have been made partners with the falsehood-asseverating devil, by believing him that they would be “like God;” and thus they would not have offended God either, as their Father, who had fashioned them from clay of the earth, as out of the womb of a mother; if they had not coveted another’s, they would not have tasted of the unlawful fruit.
