"Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth."
1st Timothy 4: 1-3
The catholic church is an apostate church that departed the scriptures and began to make it's own version of Christianity. Most of the Catholic church's version of the early church's history is fictional......starting with the myth that Saint Peter was the first Pope. Peter was married, an apostle and served as an elder of the Jerusalem congregation.
Historically there was no mention of a Pope until early into the 3rd century. Most of Catholic doctrine does not jive with Biblical scriptures. They are the result of man-made traditions and controls to empower the church in Rome and the elitists who control it's great wealth.
When Catholics go to confession, they confess their sins to God. The priest is only there to make sure they do it often. When Methodists get married, a minister officiates as an intermediary while God blesses the union. Different strokes for different folks. Diversity if great.
Perhaps, it depends upon your definition of "early". The early Christians of the Bible were "Christians", not Catholics, as mentioned in the Book of Acts, that having occurred in Antioch. The term Catholic was used later starting in the 2nd century. Extra-bilbical or anti-biblical teachings of Catholicism: forbidding clergy to marry; praying to Mary and various "saints"; definition of the term saint (proper New Testament use of term defines all believers in Jesus as "saints") - Catholics assign the term "saint" only to various notables by Papal decree; calling a Priest "Father", (worse yet) calling the Pope "Holy Father"; assumption that the Apostle Peter was the first Pope; assumption that a priest can actually convey forgiveness of sins with specific means of recompense ("Our Fathers" and "Hail Marys"); "saying or praying the Rosary" and chanting the "Lord's Prayer" - which is ironic as Jesus specifically said in that same passage of scripture, "do not pray as the heathen do, for they think they shall be heard by the much speaking"; failure to baptize by immersion; baptism for babies.
Even the Catholic Bible states in Matthew 23:8-11, "But be not ye called Rabbi: for one is you master and call no man your father upon the earth: for one is your Father, which is in heaven. Neither be ye called masters: for one is your Master, even Christ. But he that is greatest among you shall be your servant." Simply stated, the Bible condemns allowing ministers to come between us and God. Matthew 23: 8-11.
