Quotes by Tertullian
If, therefore, any one shall violently suppose that the destruction of the soul and the flesh in hell amounts to a final annihilation of the two substances, and not to their penal treatment (as if they were to be consumed, not punished), let him recollect that the fire of hell is eternal – expressly announced as an everlasting penalty; and let him admit that it is from this circumstance that this never-ending “killing” is more formidable than a merely human murder, which is only temporal.
It would be most absurd if the flesh should be raised up and destined to “the killing in hell,” in order to be put an end to, when it might suffer such an annihilation (more directly) if not raised again at all. A pretty paradox, to be sure, that an essence must be refitted with life, in order that it may receive that annihilation which has already in fact accrued to it!
In our case, murder being once for all forbidden, we may not destroy even the fetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance. To hinder birth is merely a speedier man-killing; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth. That is a man which is going to be one; you have the fruit already in the seed.
The blood of the martyrs is the seed of the Church
It is our care for the helpless, our practice of lovingkindness, that brands us in the eyes of many of our opponents. “Only look,” they say, “look how they love one another” (they themselves being given over to mutual hatred). “Look how they are prepared to die for one another” (they themselves being readier to kill each other). Thus had this saying become a fact, “Hereby shall all men know that ye are My disciples, if ye have love one to another.”
