In the Nicene Creed, Catholics profess that we believe in “one, holy, catholic, and apostolic” faith. We believe the Catholic Church is the one true Church instituted by Jesus Christ, universally practiced, and handed on by the apostles.
The Church of today is the one true Church the apostles professed. Jesus promised “there would be one flock, one shepherd” in John 10:16. Paul writes in Ephesians 4:4-5 there is one body, one spirit, one Lord, one faith, one baptism, and one God and Father. We are united into one body by the sharing of one bread (1 Cor. 10:17), which we know as the Eucharist.
Secondly, the Church is holy in that it was instituted by the all-holy God and has been endowed with the Sacraments and the Word meant to make the sinners of its body holy. This doesn’t mean that the members of the Church are perfect or “holier than thou”; it means the Church is able to dispense the graces given by Christ through the Sacraments and Holy Scripture. Christ loves us and gave Himself up for us that He might cleanse us and make us holy (Eph. 5:25-27) thereby instituting a holy Church.
Thirdly, the Church is “catholic”, meaning “universal”. Any person from any nation can be a part of the faith. It is no mere coincidence that on the “birthday” of the Church, known as Pentecost, there were Jews from every nation present when the Holy Spirit descended upon the apostles (Acts 2:5). Many accepted the faith right then and there and carried and spread the Good News in their native lands. This faith is for all people at all times in all places.
Fourthly and finally, the Church is apostolic–founded upon the apostles through the commission of Jesus. The apostles, chosen by Jesus (John 6:70), were given the power and authority to pass on the truths given to them by Jesus. The successors, or bishops, were handed over this power and authority to maintain these truths; the New Testament references this in Titus 1:5-9. All Catholic bishops to this day have the authority that originated with the apostles.
Jesus Christ founded the Catholic Church upon the authority of the apostles, available universally to all people, and instituted the Sacraments meant to make all men holy and united in His one Church. We are, and always have been, one, holy, catholic, and apostolic Church.
This series isn’t meant for debate, but simply to share what Catholics actually believe.
