I know this must sound like one of the most bizarre questions asked on AAM but I know someone who's brother is about to be made an Archbishop and was wondering what would be an appropriate present to give for someone who will be attending his ordination in Rome?
Have a look here (the shudder-inducing "Holy Land Treasures USA"). There are (unsurprisingly) a heap of ecclesiastical shops in Rome itself if the person attending has some time in Rome prior to the ordination. It might be better to get something there and ask about what's appropriate. Or ask your local PP rather than this godless lot on AAM
