What if at Liturgy there are 200 or 300 strangers around me? How am I supposed to celebrate?
One might disagree, but I say that at Liturgy it makes no difference if people know each other or have anything in common – because the fact that they are present for the Divine Liturgy forms the link between them. This is what we have in common.
We may not recognize this because we usually emphasize psychological aspects of relationships. In order to relate to someone, to show love and kindness, I need to know that person pretty well. Certainly. But the Liturgy leads us to a higher level of awareness of what it is to be human, and what it means to relate to each other. We are united by the ineluctable fact of our humanness, our baptism, our being loved by God.
