Only practical differences are considered here, with no references to the Latin Rite (Roman Rite in both cases).
Often in the USA and not so in Italy (in chronological order):
- Masses are concentrated in early morning instead of evening.
- Piano is more common than organ.
- A separate soundproof room with audio connection and big windows is available on one side of the Church.
- Missals are distributed at the beginning and collected at the end instead of leaflets available on pews.
- The celebrant starts his homily with a quip.
- People laughs openly (=higher participation versus respectful attitude).
- People are sometimes asked questions by show of hands.
- Readings, prayers and Mass formulas in English are much more direct and explicit than in Italian.
- The celebrant uses a radio microphone and moves freely in front of the altar instead of standing at the pulpit.
- Sometimes the collection basket is passed from hand to hand by rows.
- Collections can be two: for the church and for the poor.
- People queue to take the Eucharist by rows, not forming a line from random seats.
- Children who do not take the Eucharist going to the altar are blessed.
- Wine in a small glass cup is also offered in a separate line.
- Final announcements at the end are long and boring everywhere.
- Anniversaries are celebrated by applause at the end of the Mass.
- The celebrant moves to the main exit and greets the parishioners.
- A specified second collection is asked for at the end of the Mass.
- In hot places (Hawaii, Puerto Rico) air conditioning is pumped up.
- In Puerto Rico, previously recorded music is played in the background at some moments.
- Sometimes in response to "God be with you", it is said "And with your Spirit", sometimes "And also with You"
