PHILADELPHIA, Pennsylvania – As part of a fundraiser to support elderly religious, Philadelphia sisters are challenging area Catholics to a battle of wits.

CBS 3 Philly reported that a team of religious sisters will host a trivia night at 7 p.m. Aug. 28 at Maggie’s Waterfront Cafe, along the Delaware River in northeast Philadelphia.

A variety of appetizers will be provided for free, and the drink special, “Sister Mary Margaritas,” will be available for purchase.

In addition to the trivia competition, the religious sisters will also share about their lives and ministries to attendees. Bonus questions will feature trivia on Catholic sisters.

Organized by Supporting Our Aging Religious or SOAR, the sisters hope to raise awareness and funds for the needs of retired religious. The organization distributes grants to support the immediate needs of elderly religious sisters, brothers, and priests throughout the United States. Grants may go toward nurse call stations, hospital beds, handicap accessible renovations, and other necessities.

SOAR hosted a trivia night in Arlington, Virginia earlier this year, drawing a crowd of about 100.

The need for financial support for retired religious is significant, according to the U.S. bishops’ National Religious Retirement Office. A report commissioned by the office has predicted that by 2034, religious organizations may face a $9.8 billion deficit in retirement funds.
