1. The Apostles of the Lord. When our Lord and Savior Jesus Christ bid farewell to His disciples on the Mount of Olives, and ascended into heaven, He commanded them to tarry in Jerusalem until they were endued with power from on high. In this power they were to go forth into all the world and bear witness of that which they had seen and heard. He said unto them: "But ye shall receive power after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth," Acts 1, 8.
