To me, the most important missionary witness that we have is the Divine Liturgy, the Eucharistic worship of the Orthodox Church.
This is the life-giving source from which everything else proceeds. And therefore, to those who show an interest in Orthodoxy, I say, “Come and see. Come to the liturgy.”
The first thing is that they should have an experience of Orthodoxy—or for that matter, of Christianity—as a worshiping community.
We start from prayer, not from an abstract ideology, not from moral rules, but from a living link with Christ expressed through prayer.”
