Nice try. I’m not buying and you wouldn’t be either if that was coming out of Francis’ mouth.
No one claims Martin Luther was a perfect man - NO ONE is except Jesus - and Luther would have readily admitted it. But he was a godly man who sincerely tried to remedy the many abuses and corruptions he saw in the Catholic church and rather than implement the necessary changes, the powers that be excommunicated him and would have had him executed. Even Pope Benedict XVI acknowledged the deplorable shape the Roman Catholic church was in during the Reformation times.
Luther stood for the truth of the gospel which is salvation by grace through faith apart from works. That some Catholics continue to condemn the man 500 years later is really silly especially since those that do have such little knowledge of him and what he preached. I recommend this site should you ever want to read the truth about the man instead of the propaganda and lies.
