Answer: According to some statistics, Catholicism remains the most widespread religion. Islam comes second.
Step-by-step explanation:
According to available data, the number of Catholics in the world is around 2.1 billion, while Islam is second with about 1.6 billion. Therefore, both religions together have over three billion followers. Statistics also show that Islam is the fastest spreading religion in the world. This is where religion should be emphasized, because there are most people today who reject any form of worship, especially in the West.
There are several directions and sects in Islam and Catholicism, but there are two major ones in both. In Islam, these are Sunnis and Shiites, while in Christianity, they are Catholic and Orthodox. The fundamental elements of belief in both religions have not changed since the Middle Ages. Mutual intolerance began in the Middle Ages. Even today, religious intolerance and lack of understanding are prevalent among members of these religions around the world.
