According to the BBC, the three basic teachings of Christianity are that there is only one God, Jesus is the son of God and God exists as a trinity, or three parts. Christians tend to call God "Father," a practice rooted in the teachings of Jesus.
While varying sects may have different beliefs, the three basic teachings above are at Christianity's core. The BBC also lists other doctrines most Christians believe, such as life after death, communicating with God through prayer and ritual, justification through faith and baptism (a rite of initiation into Christianity). The church, or Christian community, is viewed as the core of the faith and God's body on earth.
