Timothy was one of the Seventy Apostles. He was born in Lystra in Lycaonia of a Greek father and a Jewish mother. The Apostle Paul praised his mother and grandmother because of their sincere faith (II Timothy 1:4-5). Timothy first met the great Apostle in Lystra, and was himself a witness when Paul healed the one lame from birth. Later, Timothy was an almost constant traveling companion of Paul, going with him to Achaia, Macedonia, Italy and Spain. Sweet in soul, he was a great zealot for the Faith and a superb preacher. Timothy contributed much to the spreading and establishing of the Christian Faith. Paul calls him my own son in the Faith (I Timothy 1:2). After Paul’s martyrdom, St. John the Evangelist was Timothy’s teacher. When the Emperor Dometian banished John from Ephesus to the island of Patmos, Timothy remained in Ephesus to serve as bishop. During an idolatrous feast called Katagogium, the pagans, resentful of the Christians, disguised themselves and treacherously attacked Timothy, killing him in about the year 93. His honourable relics were later translated to Constantinople and were interred in the Church of the Twelve Apostles, beside the graves of St. Luke the Evangelist and St. Andrew the First-called.

Since thou hadst been instructed in uprightness thoroughly and wast vigilant in all things, thou wast clothed with a good conscience as befitteth one holy. Thou didst draw from the Chosen Vessel ineffable mysteries; and having kept the Faith, thou didst finish a like course, O Hieromartyr and Apostle Timothy. Intercede with Christ God that our souls be saved.
