The Sign of the Cross in not to be made:
- During psalms.
- Generally, while singing.
- During litanies by the choir which will make the responses.
Making the sign of the Cross and bows are allowed after singing, not during the concluding words of a given piece.
Prostrations are not allowed on Sundays; from Nativity through Theophany; from Pascha until Pentecost Sunday; on the feast of the Transfiguration; and on the feast of the Elevation of the Cross (except the three prostrations to the Cross).
Prostrations cease with the entrance during Vespers of the feast and are not resumed until after "Vouchsafe, O Lord…" during Vespers on the day of the feast itself.
