Tertullian

Then, over our cleansed and blessed bodies willingly descends from the Father that Holiest Spirit. Over the waters of baptism, recognising as it were His primeval seat, He reposes: (He who) glided down on the Lord "in the shape of a dove," in order that the nature of the Holy Spirit might be declared by means of the creature (the emblem) of simplicity and innocence, because even in her bodily structure the dove is without literal gall. And accordingly He says, "Be ye simple as doves." Even this is not without the supporting evidence of a preceding figure. For just as, after the waters of the deluge, by which the old iniquity was purged-after the baptism, so to say, of the world-a dove was the herald which announced to the earth the assuagement of celestial wrath, when she had been sent her way out of the ark, and had returned with the olive-branch, a sign which even among the nations is the fore-token of peace; so by the self-same law of heavenly effect, to earth-that is, to our flesh -as it emerges from the font, after its old sins flies the dove of the Holy Spirit, bringing us the peace of God, sent out from the heavens where is the Church, the typified ark. But the world returned unto sin; in which point baptism would ill be compared to the deluge. And so it is destined to fire; just as the man too is, who after baptism renews his sins: so that this also ought to be accepted as a sign for our admonition.

What else did the Lord mean to show us by this example, but that we ought not to flee from persecution because it avails us nothing if God disapproves? Nay, says some one, he fulfilled the command, when he fled from city to city. For so a certain individual, but a fugitive likewise has chosen to maintain, and others have done the same who are unwilling to understand the meaning of that declaration of the Lord, that they may use it as a cloak for their cowardice, although it has had its persons as well as its times and reasons to which it specially applies. "When they begin," He says, "to persecute you, flee from city to city," We maintain that this belongs specially to the persons of the apostles, and to their times and circumstances, as the following sentences will show, which are suitable only to the apostles: "Do not go into the way of the Gentiles, and into a city of the Samaritans do not enter: but go rather to the lost sheep of the house of Israel." But to us the way of the Gentiles is also open, as in it we in fact were found, and to the very last we walk; and no city has been excepted. So we preach throughout all the world; nay, no special care even for Israel has been laid upon us, save as also we are bound to preach to all nations, Yes, and if we are apprehended, we shall not be brought into Jewish councils, nor scourged in Jewish synagogues, but we shall certainly be cited before Roman magistrates and judgment-seats.

In the same manner, therefore, we maintain that the other announcements too refer to the condition of martyrdom. "He," says Jesus, "who will value his own life also more than me, is not worthy of me," -that is, he who will rather live by denying, than die by confessing, me; and "he who findeth his life shall lose it; but he who loseth it for my sake shall find it." Therefore indeed he finds it, who, in winning life, denies; but he who thinks that he wins it by denying, will lose it in hell. On the other hand, he who, through confessing, is killed, will lose it for the present, but is also about to find it unto everlasting life. In fine, governors themselves, when they urge men to deny, say, "Save your life; "and, "Do not lose your life." How would Christ speak, but in accordance with the treatment to which the Christian would be subjected? But when He forbids thinking about what answer to make at a judgment-seat, He is preparing His own servants for what awaited them, He gives the assurance that the Holy Spirit will answer by them; and when He wishes a brother to be visited in prison, He is commanding that those about to confess be the object of solicitude; and He is soothing their sufferings when He asserts that God will avenge His own elect.

It is usual, indeed, with persons of a weaker character, to be so built up (in confidence) by certain individuals who are caught by heresy, as to topple over into ruin themselves. How comes it to pass, (they ask), that this woman or that man, who were the most faithful, the most prudent, and the most approved in the church, have gone over to the other side? Who that asks such a question does not in fact reply to it himself, to the effect that men whom heresies have been able to pervert ought never to have been esteemed prudent, or faithful, or approved? This again is, I suppose, an extraordinary thing, that one who has been approved should afterwards fall back? Saul, who was good beyond all others, is afterwards subverted by envy. David, a good man "after the Lord's own heart," is guilty afterwards of murder and adultery. Solomon, endowed by the Lord with all grace and wisdom, is led into idolatry, by women. For to the Son of God alone was it reserved to persevere to the last without sin. But what if a bishop, if a deacon, if a widow, if a virgin, if a doctor, if even a martyr, have fallen from the rule (of faith), will heresies on that account appear to possess the truth? Do we prove the faith by the persons, or the persons by the faith? No one is wise, no one is faithful, no one excels in dignity, but the Christian; and no one is a Christian but he who perseveres even to the end. You, as a man, know any other man from the outside appearance. You think as you see. And you see as far only as you have eyes. But says (the Scripture), "the eyes of the Lord are lofty." "Man looketh at the outward appearance, but God looketh at the heart." "The Lord (beholdeth and) knoweth them that are His; " and "the plant which (my heavenly Father) hath not planted, He rooteth up; " and "the first shall," as He shows, "be last; " and He carries "His fan in His hand to purge His threshing-floor."
