Timothy and Titus were converted to Christianity by St Paul, and became his companions and helpers. Paul entrusted Timothy with the care of the Christians in Ephesus, and sent Titus to Crete to look after the Christians there. He wrote them the so-called “pastoral” epistles, giving advice for pastors and people alike.
Typical of St Paul, but always worth reading again, are his letter introductions: St Paul clearly loved and cared for his missionaries!
From Paul, servant of God, an apostle of Jesus Christ to bring those whom God has chosen to faith and to the knowledge of the truth that leads to true religion; and to give them the hope of the eternal life that was promised so long ago by God. He does not lie and so, at the appointed time, he revealed his decision, and, by the command of God our saviour, I have been commissioned to proclaim it. To Titus, true child of mine in the faith that we share, wishing you grace and peace from God the Father and from Christ Jesus our saviour.
The reason I left you behind in Crete was for you to get everything organised there and appoint elders in every town, in the way that I told you.
