If Luther thought indulgences as practiced in his lifetime were Church teaching, he did not understand the teaching. As practiced, they were against the teaching. Luther "thought"??? Correction... Luther KNEW that what was practiced was permitted within the teachings of the Catholic church and approved by the Pope, who took full advantage of the massive amount of money pouring into the Vatican to fund St. Peter's Basilica. Will you also accuse Pope Leo X of permitting things that were against church teaching?
Pope Leo X:
He is probably best remembered for granting indulgences for those who donated to reconstruct St. Peter's Basilica, which practice was challenged by Martin Luther's 95 Theses. He seems not to have taken seriously the array of demands for church reform that would quickly grow into the Protestant Reformation. His Papal Bull of 1520, Exsurge Domine, simply condemned Luther on a number of areas and made ongoing engagement difficult. He did, however, grant establishment to the Oratory of Divine Love. He borrowed and spent heavily. A significant patron of the arts, upon election Leo is alleged to have said, "Since God has given us the papacy, let us enjoy it". Under his reign, progress was made on the rebuilding of St. Peter's Basilica and artists such as Raphael decorated the Vatican rooms. Leo also reorganised the Roman University, and promoted the study of literature, poetry and antiquities. He died in 1521 and is buried in Santa Maria sopra Minerva, Rome. He was the last pope not to have been in priestly orders at the time of his election to the papacy. (https://en.wikipedia.org/wiki/Pope_Leo_X)
Purgatory has Scriptural and Traditional and logical bases.[sic]
Actually, Purgatory has only a semblance of a Scriptural basis - one that is NOT explicitly found in any of the supposed passages trotted forth to support it and actually DISPROVED by actual ones. It also is not logical and the only "traditional" support is from later musings of those who failed to understand the truth of the gospel of grace.
