Notice there is nothing about holding hands or orans position, just prayerful dignity, no Happy Clappy crap.
Make the sign of the cross with holy water (a sign of baptism) upon entering the church.
Genuflect toward the tabernacle containing the Blessed Sacrament and the Altar of Sacrifice before entering the pew. (If there is no tabernacle in the sanctuary, or it is not visible, bow deeply, from the waist, toward the altar before entering the pew.)
Kneel upon entering the pew for private prayer before Mass begins.
Stand for the entrance procession.
Bow when the crucifix, a visible symbol of Christ’s sacrifice, passes you in the procession. (If there is a bishop, bow when he passes, as a sign of recognition that he represents the authority of the Church and of Christ as shepherd of the flock.)
Remain standing for the entrance rites. Make the sign of the cross with the priest at the beginning of Mass.
Strike your breast at the “mea culpa(s)” (“through my fault”) in the Confiteor.
Bow and make the sign of the cross when the priest says “May Almighty God have mercy…”
Bow your head when you say “Lord, have mercy” during the Kyrie.
If there is a Rite of Sprinkling (Asperges), make the sign of the cross when the priest sprinkles water from the aspergillum in your direction.
Throughout the Mass, bow your head at every mention of the name of Jesus and every time the Doxology [“Glory be”] is spoken or sung. Also when asking the Lord to receive our prayer.
Gloria: bow your head at the name of Jesus. (“Lord Jesus Christ, only begotten Son…”, “You alone are the Most High, Jesus Christ…” )
