Handbook of ROCOR Liturgical Practice:

A Priest with the right to wear the kamilavka (head covering) wears it at the following points during the Divine Liturgy:

  • At the Greeting of the Bishop (if a Hierarchical service); and throughout the Entrance Prayers whether or not a Bishop be present. (The kamilavka is removed only for the act of venerating the Holy Icons during these prayers, as such veneration is always done with head uncovered; and also for the prayer ‘O Lord, stretch forth Thy hand from Thy holy dwelling place on high…’, whoever is saying it [e.g. in a concelebration]; then the kamilavka is again placed on the head.)
  • After vesting, the kamilavka is again donned just before the Liturgy begins. It is normally not worn within the Altar during any preparatory works prior to the beginning of the Liturgy (and it is never worn during the Proskomedia; and whenever commemorations are made at the oblation table, during the Proskomedia or after it, the head is always uncovered for this purpose — removing the kamilavka to make commemorations as prospfora are brought in on behalf of the faithful, for example, and then returning it to the head once they are completed).
  • The kamilavka remains on the Priest’s head throughout the first parts of the Divine Liturgy. It is removed for the reading of the Holy Gospel: afterthe chief celebrant pronounces ‘Peace be upon you all’ prior to the Gospel reading, all Priests remove their kamilavkas and hold them in their left hands during the reading (they are not set aside). As soon as the Gospel reading concludes, the kamilavkas are again returned to the head.
  • The kamilavka is removed by all Priests (and set aside, thereafter remaining off) at the time of the reading of the Prayer of the Cherubic Hymn. It should be noted that a more recent custom of removing the kamilavka earlier, as the anitmins begins to be unfolded, is not the practice of our Church. It remains worn throughout the litanies that accompany the unfolding of the antimins (e.g. the Litany of Fervent Supplication, that for the Catechumens, etc.), and after the exclamation ‘That being guarded by Thy Dominion…’, immediately before the prayer of the Cherubic Hymn is read, then the kamilavka is removed and set aside.
  • The kamilavka remains off throughout the remainder of the Divine Liturgy. It is returned to the head only after the Holy Gifts have been moved to the Table of Oblation and the exclamation ‘For Thou art our sanctification…’has been pronounced, immediately before the Priest goes forth to pronounce the Prayer Before the Amvon (which should be done wearing the kamilavka), and thereafter remains on through the conclusion of the Divine Service.
