Devout "high church" Anglicans genuflect as they pass the reserved sacrament.
To "genuflect" (kneel down briefly and then arise) is the Western Orthodox way of venerating the sacrament or the altar. To take your place in church, walk quietly down the center aisle, and then genuflect before moving to the left or right into the pew. The same is done when leaving the pew, either to go up to communion or to leave after the service is over. The clergy and faithful also genuflect or bow when passing by the vessel in which the blessed sacrament is reserved. Another time to genuflect is at these words of the creed: "Who for us men and for our salvation, came down from heaven, And was incarnate by the Holy Ghost of the Virgin Mary, and was made man."
