Tertullian - Scorpiace (Antidote for the Scorpion's Sting)

This among Christians is a season of persecution. When, therefore, faith is greatly agitated, and the Church burning, as represented by the bush, then the Gnostics break out, then the Valentinians creep forth, then all the opponents of martyrdom bubble up, being themselves also hot to strike, penetrate, kill. For, because they know that many are artless and also inexperienced, and weak moreover, that a very great number in truth are Christians who veer about with the wind and conform to its moods, they perceive that they are never to be approached more than when fear has opened the entrances to the soul, especially when some display of ferocity has already arrayed with a crown the faith of martyrs. Therefore, drawing along the tail hitherto, they first of all apply it to the feelings, or whip with it as if on empty space. Innocent persons undergo such suffering. So that you may suppose the speaker to be a brother or a heathen of the better sort. A sect troublesome to nobody so dealt with! Then they pierce. Men are perishing without a reason. For that they are perishing, and without a reason, is the first insertion. Then they now strike mortally. But the unsophisticated souls know not what is written, and what meaning it bears, where and when and before whom we must confess, or ought, save that this, to die for God, is, since He preserves me, not even artlessness, but folly, nay madness. If He kills me, how will it be His duty to preserve me? Once for all Christ died for us, once for all He was slain that we might not be slain. If He demands the like from me in return, does He also look for salvation from my death by violence? Or does God importune for the blood of men, especially if He refuses that of bulls and he-goats? Assuredly He had rather have the repentance than the death of the sinner.
