In the Lords prayer what and the similarities and differences between Catholics Protestants and the Orthodox?

Answer 1

There are two versions of the prayer in Scripture, one in Matthew and the other in Luke. Some differences can be traced to these two Gospels.

Others are translation issues. The original prayer is recorded in Greek, but in English some differences can come out, such as whether you say "trespasses", "sins", or "debts". All of these are acceptable in both Catholic and Protestant circles mostly, but one translation may be more common in a particular church.

The biggest noticeable difference is whether the final doxology is added at the end of the prayer: "For yours is the kingdom, the power and the glory for ever and ever. Amen" or "The kingdom, the power, and the glory are yours now and forever. Amen"

Because this is not in the Scriptural versions, the Catholic liturgy allowed an embolism - a short prayer interjected by the priest - to occur between the main text of the prayer and the doxology. Because of this, Catholics are accustomed to praying (during the Mass) up to "...deliver us from evil" and stopping while the priest inserts his prayer, before concluding with the doxology. Most Protestants do not have this liturgical prayer inserted, so keep both parts together.

Because of this habit, Catholics often end the prayer at "...deliver us from evil" even if in fact there is no reason to do so... the Catechism of the Catholic Church even includes the Final Doxology in its section on the Lord's Prayer (2855-2865).

So, outside of the mass, Catholics could get in the habit of continuing the Lord's Prayer with the final Doxology, and this would make for less awkward moments when praying with Protestants!
