“And day by day, continuing steadfastly with one accord in the ¹temple and ²breaking bread from ³house to house, they partook of their food with exultation and ⁴simplicity of heart” (Acts 2:46)

Acts 2:46¹ temple
In the initiation of God’s New Testament economy, the early believers and even the first group of apostles were not clear that God had forsaken Judaism with its practices and facilities, including the temple (see Matt. 23:38 — “your house,” referring to the God-forsaken temple). Hence, according to their tradition and habit, they still went to the temple for their New Testament meeting.

Acts 2:46² breaking
The early believers remembered the Lord by breaking bread daily in their houses; this showed their love and enthusiasm toward the Lord.

Acts 2:46³ house
Or, at home; in contrast to in the temple. Meeting in homes as the Christian way of meeting together is fitting to God’s New Testament economy. This way differs from the Judaic way of meeting in the synagogues (6:9). It became a continual and general practice in the churches (cf. Rom. 16:5; 1 Cor. 16:19; Col. 4:15; Philem. 2).

Acts 2:46⁴ simplicity
Or, singleness; describing the heart’s being simple, single, and plain, having one love and desire and one goal in seeking after the Lord.

“Now Peter and John were going up into the ¹temple at the ninth-hour prayer” (Acts 3:1)

See note 46¹ in ch. 2 [above]. It was not only the early believers who were not clear concerning God’s New Testament economy in relation to the Judaic temple; even the early apostles did not have a clear vision concerning God’s abandoning of the Judaic things. Hence, even after God poured out the Spirit upon them on the day of Pentecost to initiate a new dispensation, they still would not separate themselves from the Judaic temple. At the initial stage God tolerated their ignorance in this matter. But this led to a mixture of the church with Judaism, which was not condemned by the early church in Jerusalem (cf. 21:20-26). Eventually, the temple was destroyed by Titus with his Roman army in A.D. 70, as prophesied by the Lord in Matt. 23:38 and 24:2. That destruction cleared up the religious mixture.
