Jesuit and Dominican Orders
Two men considering a religious vocation were having a conversation. "What is similar about the Jesuit and Dominican Orders? " the one asked.
The second replied, "Well, they were both founded by Spaniards -- St. Dominic for the Dominicans, and St. Ignatius of Loyola for the Jesuits. They were also both founded to combat heresy -- the Dominicans to fight the Albigensians, and the Jesuits to fight the Protestants."
"What is different about the Jesuit and Dominican Orders?"
"Met any Albigensians lately?"
