Mass intentions

In Paul Turner's Blog by Paul Turner

Q:  Are there any specific guidelines concerning appropriate Mass intentions. I’m thinking about an intention like, “for the intentions of John Smith.” If I don’t know his intentions, how can I pray for them? Also, can a Mass have multiple intentions if they are requested by the same person?
Thanks so much for all that you do!

A:  I found a copy of my bulletin insert on this topic on the net: http://ihmgjt2.artyrox.com/wp-content/uploads/2015/10/Mass-Intentions.pdf

The inserts are out of print now but will soon be available from LTP.
To your question, there’s nothing to stop John Smith from having us pray for his intentions, but it would be courteous for him to let us know what they are.
The question of multiple intentions is answered in the insert.
