Tertullian

“ That heretic affirmed that matter was eternal, and argued thus: ‘God was always God, and always Lord; but the word Lord implies the existence of something over which He was Lord.

“ On the doctrine of the blessed Trinity, in order to explain his meaning Tertullian borrows illustrations from natural objects. The three Persons of the Trinity stand to each other in the relation of the root, the shrub, and the fruit; of the fountain, the river, and the cut from the river; of the sun, the ray, and the terminating point of the ray. For these illustrations he professes himself indebted to the Revelations of the Paraclete. In later times, divines have occasionally resorted to similar illustrations for the purpose of familiarizing the doctrine of the Trinity to the mind ”

Without, therefore, attempting to explain, much less to defend, all Tertullian’s expressions and reasonings, we are disposed to acquiesce in the statement given by Bp. ”
