For 19 years, Vanessa Pardo dutifully followed her parents to church on Sunday mornings, reciting prayers to padre nuestro and studying la Biblia, trying to figure out how the parables of Jesus applied to her life as a member of Iglesia de Cristo en Sunset, a booming Spanish-speaking congregation in South Florida. But as the daughter of Colombian and Nicaraguan immigrants, she wasn't sure she fully understood him in Spanish, her second language. So when the Protestant congregation instituted a controversial effort last year to switch to worshipping separately in English, it immediately piqued Pardo's interest. She just had to break the news to her parents.
