On the Effects of Separation From the Church

St. Hilarion Troitsky 1886-1929
To separate, to go into isolation, is… for a Local Church the same as for a ray of sunlight to separate from the Sun, for a stream to separate from its wellspring, for a branch to separate from its trunk. The spiritual life can only exist in organic connection with the Ecumenical Church; if this connection is broken, Christian life will then unavoidably dry up. Source
