In the preaching of the Apostles to the people of their own nation, we find no intimations of any needful change in their conceptions of God, and of his mode of government. On the contrary, it was because the Jews were already prepared for their reception of Christianity by their belief in the Unity of God and the consistency of his moral government, that they were the most immediately and the most easily incorporated with the Christian church. For proof of this, we refer to the whole of the discourse delivered by the Apostle Peter on the day of Pentecost, and to every other discourse addressed by the Apostles to Jewish hearers. The first Gentiles who were converted to Christianity were not worshipers of a plurality of Gods; but men who from intercourse with Jews, or from other opportunities of spiritual advancement, had attained to the belief of One God, indivisible in his nature and unrivalled in his supremacy. The same mode of teaching which sufficed for the Jews, sufficed for them also, as far as the essential truth of Christianity was concerned; and the same method was therefore adopted, as may be seen in the discourse of Peter in the house of Cornelius. The next converts were from the disciples of the Pagan theology of Greece and Rome; with them a different method of instruction was needed. Till they knew something of the Divine nature, it was useless to open to them the Divine dispensations. The discourse of Paul at Athens did not therefore begin with announcing the Saviour: if it had, his inquisitive hearers would perhaps have inquired whether this messenger was sent by Jupiter himself, or whether he was a deputy of some of the inferior gods. The Apostle named not the name of Christ till he had taught the fundamental doctrine--that Jehovah is not only supreme, but sole; that all infinite attributes are centered in him; that all dispensations proceed from him; not only those of nature, by which the human race is created and preserved; but--the way being now prepared for the annunciation--that of grace, by which the world is to be redeemed through him whom God had ordained to be a Prince and a Saviour.
