“Different Orthodox people have different customs. Thus, in some countries it is customary to kneel during the Gospel, or during the Great Doxology at Matins, even on Sundays and between Easter and Trinity. Others may …perhaps dress for church carelessly or make the sign of the cross negligently. In such cases, we should not be tempted to pass judgement on the piety, or seeming lack of piety, of others like the foolish pharisees, but rather think of our own sins and lack of piety, seeking our salvation and not our condemnation.”
