My pastor has tried to introduce (or reintroduce?) double knee genuflection. But I see that’s not in the regulations:
84. Genuflection in the presence of the blessed sacrament, whether reserved in the tabernacle or exposed for public adoration, is on one knee.
85. For exposition of the blessed sacrament in the monstrance, four to six candles are lighted, as at Mass, and incense is used. For exposition of the blessed sacrament in the ciborium, at least two candles should be lighted and incense may be used.
Our parish uses six and two, respectively. Incense is avoided, except on Holy Thursday, per public complaint.
