For Luther, the Stumbling Block Was Papal Authority

By Mark Pattison

WASHINGTON (CNS) – The issue of papal authority was the one point that led Martin Luther to break from the Catholic Church, according to a Catholic University of America professor who spoke at a symposium on the 500th anniversary of the Protestant Reformation co-sponsored by the university.

Cajetan, a Dominican scholar who served as an aide to Pope Leo X in 1517 and had written the commentary on Thomas Aquinas’ “Summa Theologiae,” had read the writing of Luther – then an Augustinian monk – to see what was heretical in it, said Nelson Minnich, who addressed the issue of ecclesiology during the conference, May 30 – June 1.

“If he could get Luther to back down on two issues,” the problem could have been resolved, Minnich told Catholic News Service in a telephone interview.

And Cajetan was willing to give ground to Luther on the nature of salvation. But Cajetan would not back down on papal authority.

The issue played itself out over the granting of indulgences, which Luther saw the church as abusing through commercialization. “When the pope grants an indulgence, what does he absolve you of?” Cajetan asked. Luther replied, “The penal- ty the church attaches to the sin, and that’s all.”

But Cajetan responded with a quote from St. Matthew’s Gospel: “What you bind on earth shall be bound in heaven, and what you loose on earth shall be loosed in heaven.” “It’s not just the penalty on earth, but it has an effect on heaven, too. We cannot back down on this one,” Cajetan held.

Luther retorted that Cajetan’s posi- tion wasn’t Church teaching, but only Dominican teaching.

“Cajetan went back to Rome and said Luther says this view on indulgences is just Dominican teaching,” said Minnich, who teaches Church history. “He asked the pope to write a bull on this. … He spelled out Dominican teaching as the official teaching of the church,” and Luther reject- ed it as “just a rehash of what Cajetan said” with no scriptural basis.

And so began the split, with Catholics and Protestants growing more entrenched in their positions. While Catholics saw papal authority as the core issue, for Luther the prime issue was justification, according to Michael Root, another Catholic University professor, of systematic theology, who also spoke at the confer- ence. Luther argued that justification – God’s act of declaring a sinner righteous – could be achieved through faith alone. The Catholic Church held – in a position codi- fied by the Council of Trent – that faith and the sacraments were both necessary for justification.

However, ecumenical dialogue between Catholics and Lutherans resulted in a joint declaration issued in 1999 that acknowledged Luther’s position on justifi- cation. Root should know: At that time, he was executive director of the Lutheran World Federation, and a practicing Lutheran who later joined the Catholic Church.

Lutheran bodies with about 18 per- cent of world Lutheran membership rejected the declaration, however, among them the Lutheran Church-Missouri Synod, which accounts for about one-third of all U.S. Lutherans. Root said some Catholics also are bothered by the declara- tion, complaining that Roman Catholicism is “selling out to Protestants.”

Minnich said he believes the split could have been avoided had not Luther’s Catholic critics goaded him into making statements on issues he hadn’t thought through. But Root cautioned that no “great breakthrough” is on the horizon to unite the two faiths, citing such issues in the past 20 years as abortion and same-sex marriage where Catholics and Lutherans now differ.
