During the Liturgy of the Word, the concelebrants remain at their places, sitting or standing whenever the principal celebrant does. When the Alleluia is begun, all rise, except for a Bishop, who puts incense into the thurible without saying anything and blesses the deacon or, if there is no deacon, the concelebrant who is to proclaim the Gospel. In a concelebration where a priest presides, however, the concelebrant who in the absence of a deacon proclaims the Gospel neither requests nor receives the blessing of the principal celebrant.
The homily is usually given by the principal celebrant or by one of the concelebrants.
