Tertullian

But again: if the beginning passes on to the end (as Alpha to Omega), as the end passes back to the beginning (as Omega to Alpha), and thus our origin is transferred to Christ, the animal to the spiritual-inasmuch as "(that was) not first which is spiritual, but (that) which (is) animal; then what (is) spiritual," -let us, in like manner (as before), see whether you owe this very (same) thing to this second origin also: whether the last Adam also meet you in the selfsame form as the first; since the last Adam (that is, Christ) was entirely unwedded, as was even the first Adam before his exile.
