From the end of his Conflict of Religions in the Early Roman Empire:
By his expression of Christian ideas in the natural language of Roman thought, by his insistence on the reality of the historic Jesus and on the inevitable consequences of human conduct, by his reference of all matters of life and controversy to the will of God manifested in Nature, in inspiration and in experience, Tertullian laid Western Christendom under a great debt, never very generously acknowledged. For us it may be as profitable to go behind the writings till we find the man, and to think of the manhood, with every power and every endowment, sensibility, imagination, energy, flung with passionate enthusiasm on the side of purity and righteousness, of God and Truth; to think of the silent self-sacrifice freely and generously made for a despised cause, of a life-long readiness for martyrdom, of a spirit, unable to compromise, unable in its love of Christ to see His work undone by cowardice, indulgence and unfaith, and of a nature in all its fulness surrendered. That the Gospel could capture such a man as Tertullian, and, with all his faults of mind and temper, make of him what it did, was a measure of its power to transform the old world and a prophecy of its power to hold the modern world, too, and to make more of it as the ideas of Jesus find fuller realization and verification in every generation of Christian character and experience.
I’ve caught it from my “lefty” opponents for using Tertullian, but I make no apologies.
