The early Christian church was established in a Jewish land that had been influenced by Greek culture and was part of the Roman Empire. The apostles formed the backbone of the church and believers lived out their faith by bearing the Christian message in their daily lives and tasks. Christianity spread through everyday acts of compassion, concern, and love for others as believers went about their daily lives and tasks. Key factors that helped the spread of the gospel included the passion of believers, the peace of Rome, cosmopolitanism, the Jewish diaspora, and the common use of Greek as a language.
