1. “at the hour of prayer, the ninth hour” The apostles were observing the regular Jewish hours of prayer. 1st (6am), 3rd (9am), 6th (12pm), 9th (3pm). The Orthodox church has continued these hours of prayers throughout its history. The full hours follow the Jewish reckoning of time beginning the day at Evening: Vespers, Compline, Midnight Office, Matins, 1st hour, 3rd hour, 6th hour, and 9th hour.
St. Basil: “The ninth hour is enjoined on us as a necessary time for prayer by the Apostles themselves in Acts. When the day is over there comes thanksgiving for what we have been given during the day and for our achievements; and confession of our failures, our voluntary or involuntary misdeeds, and those perhaps unknown to us, whether in word or deed or in the heart itself, asking God’s mercy for all through our prayers. For a review of the past is a great help against falling again in to similar faults.”
-Chrysostom sees in this miracle and image of the Resurrection because you had a man who had been lame from birth and now was made well. It mirrors all men who are born dead and then made alive in Christ.
11. Solomon’s porch is in the temple area. In the earliest days of the Church, there was no separation between Judaism. The apostles and all the early Christian still continued to go to the temple to pray and teach. It was not until the Jewish leaders kicked them out that they began to worship separately but still maintained the Jewish synagogue styles of worship.
12-36 Peter’s Second Sermon
This sermon again follows a similar pattern to his Pentecost sermon. He points out OT fulfillment in the person of Christ. He points to everyone’s culpability in Christ’s crucifixion but the heinous act brought God’s grace and salvation. He calls the people to repentance so that they may receive God’s salvation through Jesus Christ.
-Chrysostom: they defer the glory of the act from themselves to God.
22. Deut. 18:15,18,19 This was a prophesy that Moses gave to the people of Israel as part of his last will and testament before they went into the Promised Land.
25. Gen. 22:18, 26:4, 28:14 Abrahamic Covenant
