No, not all of us have heard “Weird” Prayers of the Faithful (now called Universal Prayer), well, because our Pastor needed some help, and along with my job in music ministry, I write them! In all the years I have never heard any negative comments, except from the deacon who may kid with me over a misspelling. However, I do use a quarterly booklet that is provided by our missal provider, keeping within the them of the Mass. There are a few choices and some I skip or rewrite and keep them short. They are written in the suggested order per Fr. Zs blog. There are a couple that are on the list every week, such as praying for those have died (especially those the Mass is said for) and for their families; and, for those can not be with us due to illness, in the military, etc. The last one is always for all the prayers we hold in the silence of our hearts. Yes, the booklet has some ones that I would consider rather weird, so I avoid them.
And, actually, we don’t say “Amen,” we say “Lord, hear our prayer.”
