Click here to download the prayer of the Society. Print it out or bookmark it. There's some other material on this page that you might like to use if you want to advertise the work of the SSM in your area. Send a stamped, self-addressed envelope for prayer cards. Basically, it can cost as much as you are prepared to put into it.
Prayer is free.
If you want to copy material and hand it round or post it out, then that will cost more. It's up to you. The Society doesn't offer any share in prayers or indulgences or anything like that. In order to join, you have to say the prayer. But you can join, and pray for that person, if you like.
