Mission Statement
St. John XXIII College Preparatory forms the hearts and minds of young men and women in a Christ-centered community dedicated to academic excellence, the pursuit of virtue, and service to others in the Tradition of the Catholic Church.
St. John XXIII College Preparatory is an independent co-educational Catholic high school located in the greater-Houston suburb of Katy, Texas. Founded in 2001, our mission rests on Four Pillars which reflect the papacy of our patron, Pope St. John XXIII, and the transformative spirit of the Second Vatican Council which he convened in 1962.
Our Pillars
List of 1 items.
-
Oboedientia - Pax - Virtus - Renovatio
We accomplish our mission by forming students into men and women of character, equipping them to be successful in this life through rigorous academic study, and by fostering a love for Christ and an identity rooted in Him. Our Four Pillars provide us with a foundation for everything we do as a school - from academics and extracurricular activities to athletics and administration - in an authentic expression of the spirituality envisioned by St. John XXIII and the Second Vatican Council.

Oboedientia
Learning to trust the voice of God
As we come to know what God’s voice sounds like in Holy Scripture and the teaching of the Church, we are able to hear God’s voice everywhere and discern His calling for our lives. -
Pax
Experiencing God’s peace through liturgyWe experience wholeness within ourselves when we encounter God’s grace in the Sacraments - particularly the Mass - and when we see Him at work all around us in the symbols of our faith, the seasons of the Church year, and the lives of the patron saints of our Houses. -
Virtus
Forming character that leads to virtuous actionThe more we learn what goodness actually is - through excellence in academics, athletics, and service - the more we develop habits of virtue that allow us to lead happy, holy lives. -
Renovatio
Renewing the Church and the worldA broad and diverse education, grounded in Catholic social teaching, prepares us to become leaders in our communities, engaging with the problems of the modern world and striving for justice, mutual understanding among peoples, and the protection of human dignity.
Never hesitate to hold out your hand; never hesitate to accept the outstretched hand of another.

Papal Tiara
Though no longer in use, the triple-crown is still the heraldic coronet of the pope. It consists of three crowns to represent the pope's supreme authority as priest, prophet, and king. -
Peter's Keys
From Matt 16:19, they are a symbol of papal authority. The Keys are part of every pope's coat of arms. -
Roncalli Family Arms
St. John XXIII was born Angelo Guiseppe Roncalli, in a small town in the Lombardy region of northern Italy. He incorporated his family's coat of arms into his personal arms as bishop, then Cardinal Patriarch of Venice, and finally as Pope. -
Winged Lion
Symbol of St. Mark the Evangelist, patron of Venice, Italy. Before he was pope, St. John was the Patriarch (Archbishop) of Venice.
The latin phrase "Pax tibi Marce Evangelista meus," (Peace unto you, Mark, my Evangelist) refers to a Venetian legend that, while visiting the region, St. Mark was met by an angel who told him that the Venetian lagoon would be his final resting place.
From this symbol, we get our mascot, the Lion. Also of note, we take St. Mark as a secondary patron of the school and celebrate the Jr.
