In this article, the author discusses the most common beliefs about the origins of the Catholic Church. It is believed that the church first originated when Jesus Christ founded it in 30 A.D. The leadership of the church was mainly entrusted to the Apostles and Peter. In its early developmental stages, the church faced an abundance of conflict, such as persecution and more physical opposition as well. Despite these challenges, the church was still able to gradually develop a stable structure. After the practice of Catholicism within a larger scale was legalized, various councils even assisted the church by approving documents and doctrines and helping to establish a biblical canon.
