Hello.
The answer is: Martin Luther
One of these was the German professor-priest Martin Luther who in 1517 issued a challenge the church over this new interest in worldly affairs. He wanted the church to return to the pure (spiritual) ways of the early church--and back away from all this recent interest in power and wealth--which was rapidly corrupting it. Also, he wanted faith initiatives to be returned to the individual believer. Luther translated the Bible into German--to give the common people access to all priestly authority: the Word of God.
Have a nice day
