From its beginnings, the Church in California has been an immigrant church. Wave after wave of immigrants have arrived on California’s shores, deeply enriching Catholic life, but also creating new challenges. Women religious added to this influx. Often themselves immigrants from Europe, Mexico, Central America, Asia and Africa, sisters have often served largely the immigrant communities. California’s multi-ethnic population has created a complex mixture of languages, beliefs, and customs in the Golden State. Sisters have answered, and continue to answer, the challenges of diversity.
