The book of Acts contains several summaries (sentences) and summary narratives (paragraphs) that advance the history by synthesizing events over time into a brief or condensed statement. They accelerate the story with general declarations that depict prevailing (and healthy) church life, covering an extended but unspecified period. Some may be brief (e.g. 1:14, which cannot cover more than ten days) while others may cover time in months or years (e.g. 2:43-47).
Folks in modern academic theological circles commonly call the passages from Acts 2:42-47; 4:32-35; and 5:12-16 “summary narratives.” Lorin L. Cranford thinks 2:43-47, 4:32-35, and 5:12-16 each may cover a period of roughly five years. (I do not think I agree with that length, based on how I view the Acts timeline). The summary narratives all occur in Jerusalem.
- Acts 1:14 These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren.
- Acts 6:7 And the word of God increased; and the number of the disciples multiplied in Jerusalem greatly; and a great company of the priests were obedient to the faith.
- Acts 8:4 Therefore they that were scattered abroad went every where preaching the word.
- Acts 9:31 Then had the churches rest throughout all Judæa and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied.
