Simon is well known in the Gospels, not for his courage and faith, but for his failings (see 18:15–18, 25–27). Jesus gave him the name Cephas, an Aramaic word that means “rock.” In Greek, this name is Petros. In English, we say Peter. This name pointed to the strong church leader Simon would later become (see Acts 1:1–5:42; 8:1–12:25; 15:1–41).
