2. When in the "Teaching of the Apostles," which may be regarded here as a classic document, the discipline of life in accordance with the words of the Lord, Baptism, the order of fasting and prayer, especially the regular use of the Lord's prayer, and the Eucharist are reckoned the articles on which the Christian community rests, and when the common Sunday offering of a sacrifice made pure by a brotherly disposition, and the mutual exercise of discipline are represented as decisive for the stability of the individual community,[278] we perceive that the general idea of a pure spiritual worship of God has nevertheless been realised in definite institutions, and that, above all, it has included the traditional sacred ordinances, and adjusted itself to them as far as that was possible.[279] This could only take effect under the idea of the symbolical, and therefore this idea was most firmly attached to these ordinances. But the symbolical of that time is not to be considered as the opposite of the objectively real, but as the mysterious, the God produced ([Greek: mystêrion]) as contrasted with the natural, the profanely clear. As to Baptism, which was administered in the name of the Father, Son and Spirit, though Cyprian, Ep. 73. 16-18, felt compelled to oppose the custom of baptising in the name of Jesus, we noted above (Chap. III. p. 161 f.) that it was regarded as the bath of regeneration, and as renewal of life, inasmuch as it was assumed that by it the sins of the past state of blindness were blotted out.[280] But as faith was looked upon as the necessary condition,[281] and as on the other hand, the forgiveness of the sins of the past was in itself deemed worthy of God,[282] the asserted specific result of baptism remained still very uncertain, and the hard tasks which it imposed, might seem more important than the merely retrospective gifts which it proffered.[283] Under such circumstances the rite could not fail to lead believers about to be baptized, to attribute value here to the mysterious as such.[284] But that always creates a state of things which not only facilitates, but positively prepares for the introduction of new and strange ideas. For neither fancy nor reflection can long continue in the vacuum of mystery. The names [Greek: sphragis] and [Greek: phôtismos], which at that period came into fashion for baptism, are instructive, inasmuch as neither of them is a direct designation of the presupposed effect of baptism, the forgiveness of sin, and as besides, both of them evince a Hellenic conception. Baptism in being called the seal,[285] is regarded as the guarantee of a blessing, not as the blessing itself, at least the relation to it remains obscure; in being called enlightenment,[286] it is placed directly under an aspect that is foreign to it. It would be different if we had to think of [Greek: phôtismos] as a gift of the Holy Spirit, which is given to the baptised as real principle of a new life and miraculous powers. But the idea of a necessary union of baptism with a miraculous communication of the Spirit, seems to have been lost very early, or to have become uncertain, the actual state of things being no longer favourable to it;[287] at any rate, it does not explain the designation of baptism as [Greek: phôtismos].
