I would stay away from all of that junk. Especially Cursillo. It's all NO man centered and not God centered, and they never speak of the Blessed Virgin.
You never see these people doing real Catholic Action. Seems more like a feel-good social gathering than a religious endeavor. A lot of self promoting testimonies - that's about it. I did it 15 years ago, and even as a NO, I knew something was wrong.
