It was only when I was preparing to enter the Catholic church that I realized that the Lord's Prayer is a catholic prayer (yes, yes, Christianity is a catholic faith, but we're focused on just the prayer now, and little "c" catholic). The one word that Christ uses the most as He teaches the apostles to pray, is the word "Us", and we say it in that way whether alone or in corporate worship. If you even try to turn it from plural to singular, it will not only song oddly wrong, but also quite selfish ("give me" vs "give us"). We are a family, the body of Christ, and that was one of the lessons the Rabbi was teaching in this, the only prayer He taught us.
That many of our Protestant siblings ignore this prayer, or only say it a few times a year, is another example of their own unconscious Catholi-phobia (fear of appearing Catholic). Even calling it the "Lord's Prayer", and maybe even having it printed on nice little wooden crosses in their hall way, but rarely actually saying it.
For me, each "Us" in the prayer seems to slowly get louder, as I hear the Most Holy Trinity trying to desperately remind us that we are One body, we are One church, we are One - Universal, we are One - Catholic.
While we Catholics might sometimes self righteously act like the son who stayed, I do hope we all pray for the prodigal to return, so that our wonderful Father may rejoice in His family made whole.
Lord God, Help "Us" become holy whole again.
