Catholicism goes back to the Apostles. The word Catholic is derived from the Greek word meaning “universal”. The word universal has two ideas, the idea of one and the idea of ALL.
The first recorded use of the word Catholic is found very early in Christian literature. We find the first instance in the writings of St. Ignatius of Antioch who was a young man during the time of the apostles and the second bishop of Antioch following Peter. Ignatius was immersed in the living tradition of the local church in Antioch where the believers in Christ were first called Christians (Acts 11:26). He was alive early enough to know the apostles and was taught and ordained directly by the apostles.
Within a few short years of the Resurrection, the followers of Jesus began calling themselves “Christians” (Acts 11:26), and by the end of the first century, the word “catholic”-meaning “universal”-was applied to the Church.
The idea of different Christian denominations would have been unthinkable to the early Christians, especially in light of Christ’s pronouncement on one shepherd and one flock (John 10:15), and his prayer that his disciples remain one (John 17:22).
It was only human weakness and sinfulness that brought about the religious divisions that afflict Christianity today. The Orthodox church drew apart from Rome off and on over several hundred years, finally separating in the eleventh century.
The various Protestant denominations date back NO EARLIER than the sixteenth century, when Martin Luther decided he didn’t like some church teachings and King Henry the VIII wanted to get divorced.
These churches can trace their roots back to Christ only through the Catholic Church. Many denominations today claim as their rule of faith the Bible Alone, ironically relying on the Catholic Church for it’s canon.
Not to mention the Saints who performed 1000s and 1000s of miracles through Jesus throughout the centuries. Why is Catholicism better you ask? Go sit in a Catholic Church or an Adoration Chapel in front of the Blessed Sacrament in silence for an hour. Your question will be answered.
