Welcome & Ministry Introduction

Following St. Patrick, St. Maximilian Kolbe, and St. Francis Xavier

In a world that often feels fragmented and uncertain, we are called to live our faith with courage, beauty, and conviction. Inspired by the missionary zeal of St. Patrick, the Marian consecration of St. Maximilian Kolbe, and the pioneering spirit of St. Francis Xavier, we seek to live each day as faithful witnesses of Christ in Japan. Through deep devotion to the Immaculate Heart of Mary, the celebration of sacred tradition, and a commitment to authentic evangelization, we invite you to walk with us in this daily knightly vocation — a life of prayer, formation, and joyful witness.

聖パトリック、聖マキシミリアン・コルベ、聖フランシスコ・ザビエルに倣って

しばしば分断され、不確かな世界にあって、私たちは勇気と美しさと確信をもって信仰を生きるよう招かれています。聖パトリックの宣教の熱意、聖マキシミリアン・コルベのマリアへの奉献、そして聖フランシスコ・ザビエルの開拓者精神に触発され、私たちは日本において、キリストの忠実な証人として毎日を生きることを目指しています。汚れなきみ心の聖母への深い信心、聖なる伝統の祝い、そして本物の福音宣教への献身を通じて、私たちはあなたをこの日々の騎士的な召命——祈り、養成、そして喜びに満ちた証しの生活——へとお招きします。
