In modern practice in the Slavic tradition, when several bishops concelebrate, it is now the custom for the chief celebrant to use the great "omophorion" when called for, and the other bishops to wear the small "omophorion" throughout, with all bishops wearing their mitres. In modern Greek Patriarchal practice, on the other hand, all concelebrating bishops wear the great omophorion at the beginning of the Divine Liturgy, with only the chief celebrant wearing the mitre and the other bishops wearing their kalimavkia with the Epanokalimavkion. In other local Churches, notably the Church of Greece, all concelebrating bishops wear both the great omophorion and the mitre, and even carry their staffs.
