This depends on your view point. Apparently the Allies believed that the treaty was fair and just, but Germany did not. Personally, I think that the Treaty of Versailles was too extreme. Of course Germany had to be punished for war crimes and preventative measures had to be put in place so Germany couldn't try that again, but at the same time, if the treaty was less harsh it wouldn't have angered Germans to the point of electing the Nazi party. The German economy was already crashing and the decisions that were made in the treaty only worsened the entire establishment.
One of the major differences between the Catholic Church and the Eastern Orthodox Church is that priests can marry. Priests can marry but must do so before ordination. They can also marry in seminary.
