"hopes to see you all at this year's most beautiful day in Intramuros. December 5, 2010 at 4pm. The Grand Marian Parade. Illuminated floats, costumes, ivory images of the Virgin Mary, music, & pageantry. It's one of the best things about Catholicism in the Philippines."
I think the way to this man's heart is through the Blessed Mother.
I think the Rosary Crusade is the way to do it. Say the "Ave" and maybe say "Pray for Carlos and his followers and us sinners, now and at the hour of our death. Amen."
Praying for someone else's conversion is a Christian way to go.
