What year was the Catholic Church founded and who were its founders and administrators?
The Catholic Church, such as it was, was founded in 33 AD, 50 days after the Resurrection on the holy day of Pentecost. This is when the Apostles received the Holy Spirit, left their hiding place, and began to preach the Gospel. They were the first bishops. The founder was Jesus. He gave the Holy Spirit to the Apostle and commissioned them, saying “As the Father has sent me, so I send you.” (Jn 20:21) The first administrators were the Apostles themselves. As their ministry grew and spread, they began appointing others as bishops and priests of the Church as well. One such apostolically ordained bishop was Timothy from the New Testament. The first recorded use of the term “Catholic Church” was around 110 AD in a letter from St. Ignatius to the Smyrnaeans.
