Protestants are Christians who share the belief in God, doctrines of the Trinity, the divinity of Jesus, the death and resurrection of Jesus for salvation, and eternal life. A 'protest' against practices of the Catholic Church in 1517 by German monk Martin Luther ignited the Reformation and gave rise to Protestantism. Protestants do not believe in the authority of the Pope and hold the Bible, versus church doctrine, as the supreme and binding foundation for all Christians.
Anglican, Baptist, Congregational, Lutheran, Methodist, Presbyterian and Reformed are leading Protestant denominations today.
