From the only reliable source of Catholic news on the net, Eye of the Tiber:
According to several reports out today, the Vatican will be issuing lower back tattoos to Catholics in honor of German priest and protestant reformer Martin Luther this October.
Although Martin Luther was declared a heretic and excommunicated in 1521, Vatican officials have reportedly sent letters to all Catholics that are “able and willing” to visit Rome for the “official issuing of the ecclesiastical tramp stamp.”
“We believe that Martin Luther, though deemed a heretic by the antiquated Catholic Church, is deserving of recognition for being a witness to the gospel,” said Vatican Tramp Stamp official Eduardo Rosalini. “Also because we want people to like us. No matter whether it’s our fault or not. We do as Christ did in the Scriptures when he apologized to Pontius Pilate, blaming hypocritical members of the Sanhedrin for driving [Pilate] away from a potential conversion to Judaism.”
Rosalini went on to say that, although Catholics will not be eligible for indulgences for getting the tramp stamp due to Luther’s stance on the issue, they will, nevertheless, be compensated with salvation “no matter what sins they commit after the getting the tattoo.”
