Our greatest missionary work in life takes place in the Divine Liturgy
The Fathers of the Church would always build an Altar of Sacrifice in whatever country or city they traveled to. And this is so, because when the heart is sweetened by the Divine Liturgy, it then seeks God. It then desires to live an Orthodox ecclesiastical life, the heart of which is the Holy Eucharist.
I told the brotherhood that it should always be a priority for it to perform the Divine Liturgy in the Monastery. The prayers of the Divine Liturgy should not be intoned for personal gratification because at that moment the priests are expressing the prayers of all those praying in Church. And for this reason the priests should not be praying with self-centered feelings. We do not celebrate as individuals.
