This progress report summarizes the growth of the church thus far. It is one of seven in Acts each of which concludes a major advance of the church in its worldwide mission (cf. Acts 6:7; Acts 9:31; Acts 12:24; Acts 16:5; Acts 19:20; Acts 28:30-31). [1][source]
The believers met with one another daily, enjoying the unity of the Spirit. They congregated in the temple area probably for discussion and evangelization (cf. Acts 3:11; Acts 5:12). Probably these Jewish believers considered themselves the true remnant within Israel until they began to realize the distinctiveness of the church. They ate meals and observed the Lord"s Supper together in homes. In the ancient Near East eating together reflected a common commitment to one another and deep fellowship. A meal shared together was both a mark and a seal of friendship. In contemporary pagan religions the meal formed the central rite of the religion because it established communion between the worshippers and between the worshippers and their god. In Judaism too eating some of the offerings of worship symbolized these things, especially the peace offering. [source][source][source]
Public church buildings were unknown until the third century. At the time chapter two records, there was no significant opposition to the Christian movement, though there was, of course, difference of opinion about Jesus. The believers enjoyed the blessing of their Jewish brethren. People trusted Christ daily, and the Lord added these to the church so that it grew steadily. Luke , in harmony with his purpose ( Acts 1:1-2), stressed the Lord Jesus" work in causing the church to grow ( Acts 2:47; cf. Matthew 16:18). [source][source][source]
"... this is one of the few references in Acts to the Christians worshipping God in the sense of rendering thanks to him. The fewness of such phrases reminds us that according to the New Testament witness Christian gatherings were for instruction, fellowship, and prayer; in other words for the benefit of the people taking part; there is less mention of the worship of God, although of course this element was not absent."

"Christianity was no proletarian movement. It appealed to a broad spectrum of classes." [3][source]
