Peter's answer lays down two conditions: repentance and baptism. The former is often taken in too narrow a sense as meaning sorrow for sin, whereas it means a change of disposition or mind, which will be accompanied, no doubt, with 'godly sorrow,' but is in itself deeper than sorrow, and is the turning away of heart and will from past love and practice of evil. The second, baptism, is 'in the name of Jesus Christ,' or more accurately, '_upon_ the name,'--that is, on the ground of the revealed character of Jesus. That necessarily implies faith in that Name; for, without such faith, the baptism would not be on the ground of the Name. The two things are regarded as inseparable, being the inside and the outside of the Christian discipleship. Repentance, faith, baptism, these three, are called for by Peter.
But 'remission of sins' is not attached to the immediately preceding clause, so as that baptism is said to secure remission, but to the whole of what goes before in the sentence. Obedience to the requirements would bring the same gift to the obedient as the disciples had received; for it would make them disciples also. But, while repentance and baptism which presupposed faith were the normal, precedent conditions of the Spirit's bestowal, the case of Cornelius, where the Spirit was given before baptism, forbids the attempt to link the rite and the divine gift more closely together.
The Apostle was eager to share the gift. The more we have of the Spirit, the more shall we desire that others may have Him, and the more sure shall we be that He is meant for all. So Peter went on to base his assurance, that his hearers might all possess the Spirit, on the universal destination of the promise. Joel had said, 'on all flesh'; Peter declares that word to point downwards through all generations, and outwards to all nations. How swiftly had he grown in grasp of the sweep of Christ's work! How far beneath that moment of illumination some of his subsequent actions fell!
We have only a summary of his exhortations, the gist of which was earnest warning to separate from the fate of the nation by separating in will and mind from its sins. Swift conviction followed the Spirit-given words, as it ever will do when the speaker is filled with the Holy Spirit, and has therefore a tongue of fire. Three thousand new disciples were made that day, and though there must have been many superficial adherents, and none with much knowledge, it is perhaps not fanciful to see in Luke's speaking of them as 'souls' a hint that, in general, the acceptance of Jesus as Messiah was deep and real. Not only were three thousand 'names' added to the hundred and twenty, but three thousand souls.
III. The fair picture of the morning brightness, so soon overclouded, so long lost, follows. First, the narrative tells how the raw converts were incorporated in the community, and assimilated to its character. They, too, 'continued steadfastly' (Acts i. 14). Note the four points enumerated: 'teaching,' which would be principally instruction in the life of Jesus and His Messianic dignity, as proved by prophecy; 'fellowship,' which implies community of disposition and oneness of heart manifested in outward association; 'breaking of bread,'--that is, the observance of the Lord's Supper; and 'the prayers,' which were the very life-breath of the infant Church (i. 14). Thus oneness in faith and in love, participation in the memorial feast and in devotional acts bound the new converts to the original believers, and trained them towards maturity. These are still the methods by which a sudden influx of converts is best dealt with, and babes in Christ nurtured to full growth. Alas! that so often churches do not know what to do with novices when they come in numbers.
A wider view of the state of the community as a whole closes the chapter. It is the first of several landing-places, as it were, on which Luke pauses to sum up an epoch. A reverent awe laid hold of the popular mind, which was increased by the miraculous powers of the Apostles. The Church will produce that impression on the world in proportion as it is manifestly filled with the Spirit. Do we? The so-called community of goods was not imposed by commandment, as is plain from Peter's recognition of Ananias' right to do as he chose with his property. The facts that Mark's mother, Mary, had a house of her own, and that Barnabas, her relative, is specially signalised as having sold his property, prove that it was not universal. It was an irrepressible outcrop of the brotherly feeling that filled all hearts. Christ has not come to lay down laws, but to give impulses. Compelled communism is not the repetition of that oneness of sympathy which effloresced in the bright flower of this common possession of individual goods. But neither is the closed purse, closed because the heart is shut, which puts to shame so much profession of brotherhood, justified because the liberality of the primitive disciples was not by constraint nor of obligation, but willing and spontaneous.
