Pope Leo X, in a bull titled Decet Romanum Pontificem on January 3, 1521, excommunicated Martin Luther from the Catholic Church, as well as any who follow his teachings, whom this bull labeled Lutheran. The last part of the missive cites the authority which Leo uses to perform such excommunications. There, he wrote,
It’s possible that this bull, as well as Leo’s earlier bull, Exsurge Domine, in which he commanded Luther to recant his teaching, served as part of the influence in writing Lord, Keep Us Steadfast in Thy Word. There were later events that certainly gave cause to the hymn, not the least of which was an alliance that gave the impression that the Pope and Turk—to be understood as Muslim—were allied against the Church! Catherine Winkworth, prolific in translating many hymns into English, altered the first stanza to the way it is most often now sung, but what Luther wrote was a little closer to this:
Restrain the murd'rous Pope and Turk
Who fain would tear from off Thy throne
Christ Jesus, Thy beloved Son. (from the 1918 Evangelical Lutheran Hymn-Book)
Still, the Catholic Church, which would come to be called Roman Catholic nearly a century later, claims the authority of Peter and Paul as the founding of their church, so to speak. More specifically, the Bishop of Rome, who would call himself pope, claimed to be carrying with him and his office the authority they claim was given to Peter to be the head of the Church on earth. Peter is the foremost of all of Jesus’ apostles. Paul is the Apostle to the Gentiles. These two men have been and still are seen as the two greatest men in the Church since the Ascension of Jesus. Therefore, the papal church appeals to these for their foundation and papal authority.
