What is Christianity?Christianity is a global religion centered on the life and teachings of Jesus Christ, who followers believe is the Son of God. It's a monotheistic faith, meaning Christians believe in one God who exists in three co-equal persons: God the Father, God the Son (Jesus Christ), and the Holy Spirit. Christianity is based on the Bible, with the Old Testament and New Testament serving as sacred texts.
Who is a Protestant?Protestantism is the second largest form of Christianity with collectively more than 900 million adherents worldwide or nearly 40% of all Christians. It originated with the Reformation, a movement against what its followers perceived to be errors in the Roman Catholic Church. Ever since, Protestants reject the Roman Catholic doctrine of papal supremacy and sacraments, but disagree among themselves regarding the real presence of Christ in the Eucharist. They emphasize the priesthood of all believers, justification by faith alone (sola fide) rather than by good works, and the highest authority of the Bible alone (rather than with sacred tradition) in faith and morals (sola scriptura). The "Five solae" summarize basic theological differences in opposition to the Roman Catholic Church.
