Commandments. The Great Commission. (Joh 20:22 Mt 28:18-20 Mr 16:15-16 Lu 24:49).
1:2 After having given commandment - In the 3d verse Acts 1:3 St. Luke expresses in general terms what Christ said to his apostles during those forty days. But in the 4th Acts 1:4 and following verse s he declares what he said on the day of his ascension. He had brought his former account down to that day; and from that day begins the Acts of the Apostles.
1:1-5 Our Lord told the disciples the work they were to do. The apostles met together at Jerusalem; Christ having ordered them not to depart thence, but to wait for the pouring out of the Holy Spirit. This would be a baptism by the Holy Ghost, giving them power to work miracles, and enlightening and sanctifying their souls. This confirms the Divine promise, and encourages us to depend upon it, that we have heard it from Christ; for in Him all the promises of God are yea and amen.
