And how long shall we draw the saw to and fro through this line when we have an ancient practice which by anticipation has settled the state of the question? If no passage of Scripture has prescribed it, assuredly custom, which without doubt flowed from tradition, has confirmed it. For how can anything come into use if it has not first been handed down? Even in pleading tradition written authority, you say, must be demanded. Let us inquire, therefore, whether tradition, unless it be written, should not be admitted. Certainly we shall say that it ought not to be admitted if no cases of other practices which, without any written instrument, we maintain on the ground of tradition alone, and the countenance thereafter of custom, affords us any precedent. To deal with this matter briefly, I shall begin with baptism. When we are going to enter the water, but a little before, in the church and under the hand of the president, we solemnly profess that we renounce the devil, and his pomp, and his angels. Hereupon we are thrice immersed, making a somewhat ampler pledge than the Lord has appointed in the Gospel. Then, when we are taken up (as new-born children), we taste first of all a mixture of milk and honey; and from that day we refrain from the daily bath for a whole week. We take also in congregations, before daybreak, and from the hands of none but the presidents, the sacrament of the eucharist, which the Lord both commanded to be eaten at meal-times, and by all. On the anniversary day we make offerings for the dead as birthday honors. We consider fasting on the Lord’s Day to be unlawful, as also to worship kneeling. We rejoice in the same privilege from Easter to Pentecost. We feel pained should any wine or bread, even though our own, be cast upon the ground. At every forward step and movement, at every going in and going out, when we put on our shoes, at the bath, at table, on lighting the lamps, on couch, on seat, in all the ordinary actions of daily life, we trace upon the forehead the sign [_i.e._, of the cross]. (_b_) Tertullian, _De Baptismo_, 5-8. (MSL, 1:1314.) The whole passage should be read as showing clearly that Tertullian recognized the similarity between Christian baptism and heathen purifying washings, but referred the effects of the heathen rites to evil powers, quite in harmony with the Christian admission of the reality of heathen divinities as evil powers and heathen exorcisms as wrought by the aid of evil spirits. Ch. 5. … Thus man will be restored by God to His likeness, for he formerly had been after the image of God; the image is counted being in His form [_in effigie_], the likeness in His eternity [_in æternitate_]. For he receives that Spirit of God which he had then received from His afflatus, but afterward lost through sin. Ch. 6. Not that in the waters we obtain the Holy Spirit, but in the water, under (the witness of angels) we are cleansed and prepared for the Holy Spirit.…
