"The People of Praise also has roots in the Cursillo, an evangelistic movement founded in Spain by Catholic laymen in the 1940s, which spread to Mexico and the United States, influencing some of our founding members." (https://peopleofpraise.org/about/who-we-are/)
Full disclosure: I attended Lutheran Cursillo (back when it was still called Cursillo) in 1981, sat at the table of St. Luke.
