For those who regularly pray from the siddur, I believe you will find this of interest. I have often pondered the specifics of how The Lord’s Prayer fit in to the liturgy of Messiah’s day. Over on the FFOZ blog, Aaron Eby has made a compelling case that the Lord’s Prayer was prayed at the end of the Amidah in place of the standard conclusion known as Elohai Netzor.
The essence of his point is that Elohai Netzor was composed by Mar, son of Rabina, and taught to Mar’s disciples, as was the case with many Sages who used their own custom concluding prayer, and taught it to their disciples. As disciples of Yeshua, it would seem fitting then that we would conclude ha Tefillah with His prayer.
