“The Lord’s Prayer is Protestant?”
The Protestant version, yes.
Protestant ending to the “The Lord’s Prayer”.
“For thine is the kingdom, and the power, and the glory, for ever and ever. Amen”
The doxology of the prayer is not contained in Luke’s version, nor is it present in the earliest manuscripts of Matthew, representative of the Alexandrian text, but is present in the manuscripts representative of the Byzantine text. It is thus absent in the oldest and best manuscripts of Matthew, and most scholars do not consider it part of the original text of Matthew. Modern translations generally omit it.
And it differs how?
