Genuflecting to the Blessed Sacrament and to the Cross
Sometimes people will ask: “Why do we genuflect before we enter a pew in church?” Another way of phrasing the question would be: “Why do we genuflect when we come into church?” A genuflection is seen by the Church as a sign of reverence that signifies adoration. It is for that reason that Catholics genuflect to the Blessed Sacrament when they come into a church. A genuflection is made by bending only the right knee to the ground. This is done whether the Blessed Sacrament is reserved in the tabernacle or exposed for adoration. This sign of reverence is the same as that of the priest who genuflects on one knee at Mass after the consecration of the Host or the Precious Blood, and also before he shows the Host to the people before Communion.
The genuflection is also made to the cross from the time of solemn adoration of the cross in the Good Friday liturgy until the beginning of the liturgy of the Easter Vigil.
No genuflection is ever made by those who are carrying something that is used in the liturgical celebration, for example, the censer, the cross, candlesticks, or the Book of the Gospels.
