Too many times, he says, someone will receive the Host in the hands and then, for some unknown reason, not consume it.

Over the last several weeks, many different prelates around the world have issued public statements raising concerns about the state of the liturgy. The head of the Vatican's Congregation for Divine Worship, Cdl. Robert Sarah, says Vatican II's teachings on the liturgy have yet to be truly carried out. He recently criticized a mistaken notion of "active partipation" by laymen at Mass and went on to call for a return to ad orientem worship, where the priest and people face eastward together toward the altar.
A bishop in Brazil, Milton Kenan Junior, has also had to correct his flock's understanding of liturgical norms, too, specifically when it comes to the sign of peace and extraordinary ministers of holy Communion.
