A rather interesting idea is presented here. On the fundamental level of comparison, a principle of the Renaissance was the idea that individuals think for themselves as the movement glorified the exploits of the individual and the glory of the human being. In many senses, the Reformation lauded the individual's ability to determine for themselves how their religious state of being should be pursued and to not be limited by a corrupt institution. The exploration of different paths towards knowledge was present in the Renaissance, as the idea was that humans are not limited in a world of promises and possibilities. At the same time, the Reformation encouraged individuals to find different paths to religious salvation.
The two movements were similar in that both were a break from the usual. They were both the catalysts of social change that transformed an era, and brought in some of the richest moments in history.
From the Renaissance, we have names such as Michaelangelo, Da Vinci, Bramante, and Raphaelyn, in England there is the house of Tudor with Henry VIII and Anne Boleyn. In art, we returned to the Classics, and embraced the purity of the human body, and of beauty. We questioned feudalism, the stars, and our role in the solar system. We financed our way away from the peasantry and developed a burgioisie. Authority was consistently questionned.
From the Reformation, we have also high profile names like Martin Luther, Sir Thomas Moore, Cardinal Wolsey, and other huge transformators. While the Renaissance returned to the classics, the Reformation returned to the original teachings of religion, which were far removed from Popes in princely robes, orgies in cathedrals, and the selling of indulgences. Similarly to the Renaissance, the authority of religious leaders was questioned, and put in danger. It was time for a break in tradition.
To some extent, I think this is true.
The Renaissance was a time when people started to think about the world in a more scientific way. Instead of relying on past authorities, or on the authority of the Church, they started to think about things for themselves.
In a sense, the Reformation did the same thing. One of Luther's major ideas was that people should read the Bible for themselves and think for themselves. He did not believe in simply following what the Church hierarchy said.
So, in that way, both movements encouraged more thinking and less blind reliance on authority.
