Here’s an interesting site that I just found: 40 Prayers for 40 Days, run by the Catholic Medical Mission Board, since 1928. In their own words:
Easter is a time of renewal and celebration for people around the world. Sadly though, many children, women, and men in developing nations have little reason to celebrate. They are dying from preventable and treatable diseases simply because healthcare is a luxury that few can access. That’s why CMMB’s work is so critical. Please take a moment to explore the lifesaving work that CMMB does around the world, and consider supporting this vital work with a generous gift. With your help, people will be healed and made whole. That’s a remarkable way to commemorate this Easter.
