The Formulae of Baptism in Acts and the Epistles (In relation to Matt. 28:19, 20).

185. THE FORMULAE OF BAPTISM
IN ACTS AND THE EPISTLES
(In relation to Matt. 28:19, 20.)

To some, perplexity, and even distress, is caused by the apparent neglect of the disciples to carry out the Lord's command in Matt. 28:19, 20, with regard to the formula of baptism. They read the express words of the risen Lord in the Gospel: then, turning to Acts and onwards, they find no single instance of, or reference to, baptism in which the Triune name of Father, Son, and Holy Spirit is employed.
On the contrary, from the very first, only ten days after the injunction had been given, Peter is found (Acts 2:38) commanding all his hearers including those of the dispersion (the diaspora) to be baptized in (the texts, except T, read en, not epi, nor eis as in Matt. 28:19) the name of Jesus Christ. Acts 8:16 (eis); 10:48 (en); 19:5 (eis), are in accord, the formula being in or into the name of the Lord, or the Lord Jesus. In the last case, whether this refers to those who heard John or Paul, or whether the baptism was that of John or Paul, the formula is the same. Rom. 6:3, -- "as many of us as were baptized into (eis) Christ Jesus". 1Cor. 1:13, 15; here baptism "in (eis) the name of Paul" is clearly contrasted with baptism in the name of the Lord Jesus, or Christ Jesus, which must have been used as to Crispus, Gaius, and Stephanas.
In all the other places where the act of baptism is mentioned, directly or indirectly, the formula by implication is the same. These are: Acts 8:38; 9:18 (and 22:16); 16:15, 33; 18:8. Yet on the other hand there stands the definite command in Matt. 28:19, 20, as to the discipling of THE NATIONS into (eis) the Triune name of the Father, Son, and Holy Spirit.
The "difficulty" is created by non-observance of the injunction in 2Tim. 2:15 as to "rightly dividing the word of truth". It comes by mixing up and thus confusing the "mystery" (Ap. 193) concerning the church of God during the "times of the Gentiles" with the ordinances and observances of the "times" of Messiah (Isa. 33:6), with which the command in Matt. 28:19, 20 has clearly to do, as the discipling of the nations AS NATIONS, is expressly declared. It is the commission of the Jewish ministry at the end of this age. There is nothing corresponding to this form of baptism in any of the foregoing passages (2), all of which are connected with individuals or families. Inasmuch as the mystery is the great secret which was "kept secret since the world began" (Rom. 16:25; cp. Eph. 3:9; Col. 1:26), it follows logically that it must not be read into the Gospels.
The "discipling" work of Matt. 28:19, 20 is national work: its object -- to bring all nations into blessing with Israel. It has nothing to do with the present dispensation and the "one baptism" (Eph. 4:5) of this dispensation. Matt. 28:19, 20 takes up the proclamation of the kingdom, left uncompleted in Matt. 10:5-15, after the church has been called on high. Therefore, the baptism "in" or "into" the name of the Lord Jesus in Acts, &c, was the continuation of John's baptism for a while, i.e. during the transitional period of Acts (see App. 180, 181) until the mystery was openly revealed and fully proclaimed (see Longer Note, p. 1694). Then, the baptism of Eph 4:5 supervened and still maintains.
To hold, as some do, that the disciples had "forgotten", or were "ignorant of", or else "ignored" the express command of the Lord, is to charge those spirit endowed men with either incompetence or insubordination! Peter and John and the rest must have known well the meaning and future reference of Matt. 28:19, 20; and they knew of John's baptism also: but until "led on" into more of "all the truth", by the Holy Spirit, and until the revelation of the secret concerning the church which is His body was declared, they continued to baptize, as John had done, into the name of the Lord Jesus.
This explanation does no violence to the Word of God. It does not impugn the intelligence or bona fides of the disciples. It leaves each of the several Scriptures unscathed and in its proper place, and each as being absolute truth. What it really "touches" is tradition only and the teaching based thereon.
