Catholicism is the largest religion in terms of members and apparently one of the oldest that has been established. Their main focus is to spread Christianity all throughout the world. According to our history, other religions have been formed through inspiration of the Catholic movement. Some go against the Catholicism and form other religions that "seems" to battle out with principles and ideals.
There are lots of traits that other religion can learn from the Catholic Christians. We can summarize it as devotion, traditions and example. Other religions can also learn the importance of leadership and organization of church activities. Some of the other religions have tried to cope with the style of the Catholic ways in terms of Sunday services, holidays, beliefs and ideals.
