[T]he Father, the Son, and the Holy Ghost [are] three ... not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost.
TertullianFor it is really better for us not to know a thing, because [God] has not revealed it to us, than to know it according to manโs wisdom, because he has been bold enough to assume it.
TertullianWoman, thou shouldst ever be clothed in rags and in mourning, appearing only as a penitent, drowned in tears, and expiating thus the sin of having caused the fall of the human race. Woman thou art the gate of the devil. It is thou who hast corrupted those whom Satan dare not attack face to face.
Tertullian
