Christian doctrines are the core beliefs and teachings that define the Christian faith. These doctrines include the belief in the Trinity, which describes God as three persons in one: God the Father, God the Son (Jesus Christ), and God the Holy Spirit. Other key doctrines include the belief in the resurrection of Jesus, salvation through faith, and the authority of the Bible. Different Christian denominations may interpret these doctrines in various ways, leading to diverse practices and beliefs. For example, Catholicism emphasizes the sacraments, while many Protestant groups focus on personal faith and scripture. Despite these differences, the central tenets of Christianity remain foundational to all believers.
