Iglesia Hispana Adventista del Séptimo Día is a Spanish-language Seventh-day Adventist congregation in Carlsbad, holding Saturday Sabbath services on Eureka Place in the 92008 zip code. All worship, Bible study, and pastoral counseling are conducted in Spanish, addressing the same linguistic needs in faith settings that Carlsbad City Library serves through its multilingual resource collections. The church follows the global Seventh-day Adventist liturgical calendar, with Saturday Sabbath observance rooted in the denomination's 1863 founding in Battle Creek, Michigan. A graded Sabbath School program teaches children ages three through seventeen using the denomination's quarterly international lesson curriculum, building a structured faith-education track alongside Carlsbad's broader early-childhood ecosystem, where Highland Preschool on El Camino Real provides a parallel developmental curriculum. The Seventh-day Adventist Church operates Loma Linda University Medical Center and more than 200 hospitals worldwide, making this Carlsbad congregation part of the largest Protestant-run healthcare and education network on the planet.
