Archbishop Anastasios of Albania on missions:

“Missions is not an appendix of our faith, of our own Church life, it belongs in the essence of our own identity.”

“Missions is an essential expression of Orthodox self-conscience, a crying out to action for the fulfillment of God’s will ‘on earth as it is in heaven.’  Ultimately, indifference to missions is a denial of Orthodoxy.”

“Orthodox mission consists in giving the treasure we have, and leaving the other to decide whether he will take it or not. If the other wants to join the Orthodox Church, you will never say “No.” Our aim is to transmit the tradition of the Gospel in all its fullness, remaining free from any anxiety to convert anyone. You cannot impose on anyone’s freedom. You are there, you give your witness; you are a candle, lighted by paschal joy, and if the other wishes to take from your flame, then of course, you will not refuse him.”
