‘Sent into the world on my errand.’ The word apostle signifies one who is sent.
Who sends, to whom, and why? Christ is the sender. To whom does Christ send his apostles? To the whole world. The Kingdom of God has no visible frontiers, it is within the heart of each human being. ‘Go out all over the world and preach the gospel to the whole of creation’ (Mark xvi, 15). What is Christ's errand? To deliver the message 'which concerns the Word who is Life'.
‘What he was from the first, what we have heard about him, what our own eyes have seen of him, what it was that met our gaze and the touch of our hands.’ (I John i, 1.) Why is the message delivered? ‘That you too may share in our fellowship … with the Father and with his Son Jesus Christ.’
