In spite of claims that the doctrines of Protestantism are closer now to those of the Roman Catholic Church, this article explains that there remains a vast difference between the two traditions. It considers such differences in the doctrines of justification, Scripture and tradition, church and sacraments, Mary and the saints, indulgences, and purgatory.

This article looks at the Roman Catholic concept of apostolic succession. It explores how this concept emerged out of an episcopalian church government and an understanding of the interconnection of Christ and his church. It then follows up with what evangelicals believe concerning apostolicity, namely, the Word-centredness of the church that has as its focus the writings of the apostles.
