Common Question: Where is the last line of the Lord's Prayer?
A common question I get when we study the Lord’s Prayer is this: “Where is the ending of the Lord’s Prayer? Why isn’t the line ‘For Thine is the Kingdom, power and glory forever and ever. Amen!’ there?”
The answer is that the best early manuscripts of the Greek text do not contain the ending because Jesus never said that part. Most Jewish prayers ended with a free-verse doxology as in 1 Chronicles 29:11-12. By the second century we begin to see the Lord’s prayer written with a final doxology, “For thine is the Kingdom and the power and the glory forever and ever. Amen!” This ending may have been part of the verbal transition as early as the disciples, but we can’t know for sure. What we do know is that the doxology is included with the prayer by the end of the second century has been put to common use by the Church since that time.
