Answer:
The age of faith is the period when when everybody (Medieval Europe that is) embraced a homogenous, superstitious, and bigoted Christianity. The age of feudalism is when the feudal system took place; division of upper and lower classes were there. the age of chivalry is the time of the chivalry civilization. A time were men were courageous and courteous and women were fair and respected. The most valid (to me) is the age of chivalry because it gave equality to everyone.
