The Church — One, Holy,
Catholic, and Apostolic
The Church is the community founded by Christ, sustained by the Holy Spirit, and marked by four essential characteristics—one, holy, catholic, and apostolic—which reveal her identity and mission in the world.
Meaning
ONE — United in Faith, Worship, and Leadership
The Church has one Lord, one faith, one baptism (Eph 4:5). Her unity comes from Christ and is sustained by the Holy Spirit. This unity is visible in common doctrine, shared sacramental life, and communion with the Pope and bishops.
Why It Matters
The Church’s unity is a sign to the world that God gathers all people into one family.
Meaning
HOLY — Filled with God’s Life and Called to Sanctity
The Church is holy because God is holy. The Holy Spirit dwells within her, guiding and sanctifying her through holy doctrine, holy sacraments, and the witness of holy saints.
Why It Matters
Even though her members are sinners, the Church remains holy because her source—Christ—is holy, calling all people to holiness.
Meaning
CATHOLIC — Universal in Mission and Complete in Faith
Catholic means universal and whole. The Church proclaims the fullness of faith, possesses the full means of salvation, and is sent to all peoples, cultures, and nations.
Why It Matters
The Church is not limited to one group or region; she is for everyone, everywhere, always.
Meaning
APOSTOLIC — Founded on the Apostles and Guided by Their Successors
Christ built the Church on the apostles. This foundation continues through apostolic succession, the Magisterium, and fidelity to apostolic teaching.
Why It Matters
The Church remains rooted in Christ’s original mission and protected from error in matters of faith and morals.
