The Orthodox Church was founded by our Lord Jesus Christ, when after His Ascension, He sent down upon His Apostles the Holy Spirit who proceeds from God the Father as is written in the New Testament. The Orthodox Church of today can trace its history back to the New Testament Church in unbroken continuity. The Apostles, as per our Lord's command, preached the Gospel of Jesus Christ and founded churches in Europe, Asia and Africa. Under the direction of the Apostles and their successors, whom they appointed to carry on their mission, the Orthodox Church began to thrive. At each city and town that the Apostles traveled they would appoint a bishop to continue to minister to the faithful, before leaving on their missionary journeys. As the Church grew, the bishops in turn had to appoint priests and deacons to help them with their flock.
