The belief that the only justifiable Christian
belief is that taken directly from the text of the Bible
Originally championed by Ulrich Zwingli and taken on by many other reform churches in the form of Evangelism.
Similar in many ways to sola fide, the belief of Martin Luther.
Disputed by the Catholic Church on the basis that the Pope is the only person who can interpret the bible. Discounted by catholicism at the Council of Trent.
