“Assurance of salvation” in a time of eschatological expectation demanded some kind of security for the future of which the earnest could be possessed in the present. And with this the predestinarian thought of election was in complete accord. If we find the thought of being sealed unto salvation previously in the Psalms of Solomon, and subsequently in the same signification in Paul, in the Apocalypse of John, and down to the Shepherd of Hermas, it may be assumed in advance that it will be found in some form or other in the so strongly eschatological teaching of Jesus and the Baptist.
It may be said, indeed, to dominate completely the eschatological preaching of the Baptist, for this preaching does not confine itself to the declaration of the nearness of the Kingdom, and the demand for repentance, but leads up to an act to which it gives a special reference in relation to the forgiveness of sins and the outpouring of the spirit. It is a mistake to regard baptism with water as a “symbolic act” in the modern sense, and make the Baptist decry his own wares by saying, “I baptize only with water, but the other can baptize with the Holy Spirit.” He is not contrasting the two baptisms, but connecting them—he who is baptized by him has the certainty that he will share in the outpouring of the Spirit which shall precede the judgment, and at the judgment shall receive forgiveness of sins, as one who is signed with the mark of repentance. The object of being baptized by him is to secure baptism with the Spirit later. The forgiveness of sins associated with baptism is proleptic; it is to be realised at the judgment. The Baptist himself did not forgive sin.[289] If he had done so, how could [pg 377] such offence have been taken when Jesus claimed for Himself the right to forgive sins in the present (Mark ii. 10).
The baptism of John was therefore an eschatological sacrament pointing forward to the pouring forth of the spirit and to the judgment, a provision for “salvation.” Hence the wrath of the Baptist when he saw Pharisees and Sadducees crowding to his baptism: “Ye generation of vipers, who hath warned you to flee from the wrath to come? Bring forth now fruits meet for repentance” (Matt. iii. 7, 8). By the reception of baptism, that is, they are saved from the judgment.
As a cleansing unto salvation it is a divine institution, a revealed means of grace. That is why the question of Jesus, whether the baptism of John was from heaven or from men, placed the Scribes at Jerusalem in so awkward a dilemma (Mark xi. 30).
The authority of Jesus, however, goes farther than that of the Baptist. As the Messiah who is to come He can give even here below to those who gather about Him a right to partake in the Messianic feast, by this distribution of food to them; only, they do not know what is happening to them and He cannot solve the riddle for them. The supper at the Lake of Gennesareth was a veiled eschatological sacrament. Neither the disciples nor the multitude understood what was happening, since they did not know who He was who thus made them His guests.[290] This meal must [pg 378] have been transformed by tradition into a miracle, a result which may have been in part due to the references to the wonders of the Messianic feast which were doubtless contained in the prayers, not to speak of the eschatological enthusiasm which then prevailed universally. Did not the disciples believe that on the same evening, when they had been commanded to take Jesus into their ship at the mouth of the Jordan, to which point He had walked along the shore—did they not believe that they saw Him come walking towards them upon the waves of the sea? The impulse to the introduction of the miraculous into the narrative came from the unintelligible element with which the men who surrounded Jesus were at this time confronted.[291]
The Last Supper at Jerusalem had the same sacramental significance as that at the lake. Towards the end of the meal Jesus, after giving thanks, distributes the bread and wine. This had as little to do with the satisfaction of hunger as the distribution to the Galilaean believers. The act of Jesus is an end in itself, and the significance of the celebration consists in the fact that it is He Himself who makes the distribution. In Jerusalem, however, they understood what was meant, and He explained it to them explicitly by telling them that He would drink no more of the fruit of the vine until He drank it new in the Kingdom of God. The mysterious images which He used at the time of the distribution concerning the atoning significance of His death do not touch the essence of the celebration, they are only discourses accompanying it.
On this interpretation, therefore, we may think of Baptism and the Lord's Supper as from the first eschatological sacraments in the eschatological movement which later detached itself from Judaism under the name of Christianity. That explains why we find them both in Paul and in the earliest theology as sacramental acts, not as symbolic ceremonies, and find them dominating the whole Christian doctrine. Apart from the assumption of the eschatological sacraments, we can only make the history of dogma begin with a “fall” from the earlier purer theology into the sacramental magical, without being able to adduce a single syllable in support of the idea that after the death of Jesus Baptism and the Lord's Supper existed even for an hour as symbolical actions—Paul, indeed, makes this supposition wholly impossible.
In any case the adoption of the baptism of John in Christian practice cannot be explained except on the assumption that it was [pg 379] the sacrament of the eschatological community, a revealed means of securing “salvation” which was not altered in the slightest by the Messiahship of Jesus. How else could we explain the fact that baptism, without any commandment of Jesus, and without Jesus' ever having baptized, was taken over, as a matter of course, into Christianity, and was given a special reference to the receiving of the Spirit?
It is no use proposing to explain it as having been instituted as a symbolical repetition of the baptism of Jesus, thought of as “an anointing to the Messiahship.” There is not a single passage in ancient theology to support such a theory. And we may point also to the fact that Paul never refers to the baptism of Jesus in explaining the character of Christian baptism, never, in fact, makes any distinct reference to it. And how could baptism, if it had been a symbolical repetition of the baptism of Jesus, ever have acquired this magic-sacramental sense of “salvation”?
Nothing shows more clearly than the dual character of ancient baptism, which makes it the guarantee both of the reception of the Spirit and of deliverance from the judgment, that it is nothing else than the eschatological baptism of John with a single difference. Baptism with water and baptism with the Spirit are now connected not only logically, but also in point of time, seeing that since the day of Pentecost the period of the outpouring of the Spirit is present. The two portions of the eschatological sacrament which in the Baptist's preaching were distinguished in point of time—because he did not expect the outpouring of the Spirit until some future period—are now brought together, since one eschatological condition—the baptism with the Spirit—is now present. The “Christianising” of baptism consisted in this and in nothing else; though Paul carried it a stage farther when he formed the conception of baptism as a mystic partaking in the death and resurrection of Jesus.
