The Congregation of the Clarisas Missionary Sisters of the Blessed Sacrament was founded by Mother María Inés Teresa Arias in Cuernavaca, Morelos, Mexico, on August 23, 1945.
In 1951, having received the decree of Pontifical approval for the foundation, she sent the first “Ad Gentes” missionaries to different parts of the world. All of them were imbued with the very spirit of their Foundress, burning with apostolic zeal, offering themselves for the salvation of souls.
The motto “OPORTET ILLUM REGNARE” (He must reign) expresses the mission of the Clarisa Missionary Sister of the Blessed Sacrament, who embraces the duty of evangelization as her very own, sharing the Church’s responsibility to proclaim the Gospel message to every human person across all social, cultural, and economic backgrounds, regardless of race or beliefs.
In this spirit of making God’s mercy known to all, the Clarisa Missionary Sister, living a contemplative-active life, commits herself to the specific apostolates of the Congregation and bears witness to fraternal love, always in a spirit of understanding and service, lived in love and peace—charity being what impels her to live no longer for herself, but for every soul in need. With the sole purpose of bringing the Gospel of Christ and giving glory to God, she lives her vows of chastity, poverty, and obedience, offering herself from the moment of her entrance for the salvation of souls, and living in accordance with the charism of her Foundress and the Constitutions approved by the Holy See.
To date, the Clarisas Missionary Sisters of the Blessed Sacrament are present in: Mexico, Japan, the United States, Costa Rica, Indonesia, Italy, Spain, Nigeria, Korea, India, Russia, Argentina, Sierra Leone, Liberia, Ireland, and Vietnam.

On June 22, 1951, we received the Decree of Pontifical Approval, a milestone that consolidated our identity as an Institute of Pontifical Right. The Church recognized our mission to bring Christ to every corner of the world.
This recognition urged us to expand our work, always faithful to our Eucharistic and Marian charism, trusting in Divine Providence at every step of our missionary journey.

Our spirituality is a path of love and trust, founded on the will of God and lived with profound joy.

Perpetual Adoration and total surrender to Christ in the Eucharist, the source and summit of our life and mission.

We offer our daily prayer and sacrifice for the sanctification and support of priests.
La opción principal y más equilibrada.

We bring the joy of the Gospel and the proclamation of salvation to all peoples without distinction.

Joy is the most convincing witness that there is no greater fulfillment than serving God. It is not a superficial laughter, but the inner peace of one who knows they are deeply loved by the Father.

We live under the protective mantle of the Virgin Mary, model of faith, purity, and absolute trust.
We journey accompanied by the intercession of those who are models of fidelity and total devotion to the Kingdom of God.

Let not your heart be troubled... Am I not here, who am your Mother?

The life of every Clarisse Missionary is centered not on what she does, but on the One who sustains her. For us, the Eucharist is the foundation that gives life to every project and every community. It is not merely a rite; it is the promise of abiding presence: “Whoever eats my flesh and drinks my blood remains in me and I in him” (Jn 6:56).
Living this spirit means learning to offer one’s own heart as an altar. It is the beauty of allowing oneself to be transformed by Jesus in the Blessed Sacrament until one’s very life becomes, simply, ‘broken bread.’ In the joy of daily self-giving, we unite ourselves to the sacrifice of Christ so that His love may reach, like a fire of hope, the farthest corners of the earth. For us, Jesus in the Eucharist is everything. He is the One who guides us, who loves us, and who gives us strength. The Mass, adoration, and everything surrounding the Blessed Sacrament is the center of our lives. It is the food that nourishes our soul and heart.

There is a profound beauty in a surrender that holds nothing back. The priestly spirit invites us to live as ‘offerers of ourselves,’ bringing to life the words of Saint Paul: ‘Present your bodies as a living sacrifice, holy and acceptable to God’ (Rom 12:1).
This vocation reaches its fullness at the foot of the Cross. It is not a path of resignation, but of infinite trust. In the silence of the heart, we embrace daily challenges as opportunities to grow in love for our ‘Divine Lover.’ It is the joy of knowing that each small sacrifice, offered with generosity, becomes a fruitful cooperation with God’s work in the world. We feel that Jesus invites us to follow Him closely, just as He did in His public life, giving Himself entirely to others. We too desire to live this way: giving of ourselves without reserve and giving thanks for the opportunity to offer our lives out of love, just as He did. We long to be a kind of ‘living offering,’ united with Jesus the Priest, for the good of all.

Mission is not an activity we perform; it is our very reason for being. We are moved by an insatiable longing for the light of the Risen Christ to reach every corner of the earth. This missionary spirit is born of a deep interior life, for we understand that one can only give what has first been received in prayer. Our way of being missionaries does not always mean traveling and preaching with words. Often, our mission is to pray, to offer sacrifices, and to remain available to help in the conversion of hearts. Through prayer and service, we seek to draw people closer to the love of God.
o be missionaries is our most sacred duty and our sweetest right, and we bring it to life:
With the suitcase of our hearts always packed to be witnesses of hope in a world thirsty for God.

Rejoice in the Lord always” (Phil 4:4). In a Clarisse Missionary, joy is the most compelling witness that there is no greater fulfillment than serving God. It is not a superficial laughter, but the intimate peace of one who knows she is deeply loved by the Father.
The heart of every Clarisse Missionary aspires to be a lyre from which hymns of love and gratitude arise. This ‘holy joy’ accompanies us at all times, especially when circumstances call us to bring comfort to others. It is the radiance of a will that has found its rest in service. Joy is a hallmark we long to carry always. Our smile is not merely outward; it is the expression of what we feel within: a profound gratitude for being called by God and loved by Him. That joy springs from knowing we are His, from knowing that our vocation is a gift.

For the Clarisse Missionary, the Blessed Virgin Mary is not merely a figure of devotion, but the ‘soul of our soul.’ At the foot of the Cross, we take her into our home and into our heart, never to be separated from her.
Our charism is deeply Marian and Guadalupan. From her, we learn the art of generosity and the courage of the ‘Fiat’—that constant ‘yes’ to the promptings of the Lord. We count ourselves blessed to walk under her mantle, knowing that her maternal warmth brings life to our works and teaches us to be instruments of peace. With Mary, the path to the Heart of Jesus becomes shorter, surer, and filled with light. We hold a very special love for the Virgin Mary. She is our Mother, our guide, and our refuge. In particular, we honor Our Lady of Guadalupe as our patroness. To her, we entrust our dreams, our missions, and the conversion of souls. .
San José fue el esposo de la Virgen María y el padre adoptivo de Jesús. La Biblia nos lo presenta como un hombre bueno, justo y trabajador. Era carpintero y artesano, y con su esfuerzo cuidó y sostuvo a la Sagrada Familia.
Su vida nos enseña el valor del trabajo hecho con amor y dedicación, y cómo desde lo sencillo se puede colaborar en los planes de Dios.
San José es patrono de toda la Iglesia, y también es copatrono de nuestra Congregación, las Misioneras Clarisas del Santísimo Sacramento. Desde los inicios, Madre María Inés lo eligió como protector de esta obra misionera, confiando en su ayuda y guía para acompañar a los misioneros en su camino.
Hoy seguimos sintiendo su cercanía, su silencio lleno de fe y su protección como padre amoroso.
La Virgen de Guadalupe se apareció en 1531 a Juan Diego, un hombre sencillo y creyente, en el cerro del Tepeyac (hoy parte de la Ciudad de México). Le pidió que se construyera un templo en ese lugar, como muestra de su amor y cercanía con su pueblo.
Desde entonces, la Virgen de Guadalupe es una madre muy querida, especialmente por los pueblos de América Latina. Ella es un símbolo de consuelo, esperanza y ternura para quienes confían en su intercesión.
Para nosotras, las Misioneras Clarisas del Santísimo Sacramento, la Virgen de Guadalupe tiene un lugar muy especial. El 12 de diciembre de 1930, durante su profesión religiosa, nuestra fundadora Madre María Inés Teresa vivió una experiencia espiritual profunda: sintió en su corazón que la Virgen le prometía acompañarla en su misión y darle las gracias necesarias para tocar los corazones de muchas personas
Desde ese día, María de Guadalupe es nuestra patrona y madre espiritual, y sabemos que camina con nosotras en cada paso de nuestra vocación misionera.

La alegría es una marca que queremos llevar siempre. Nuestra sonrisa no es solo por fuera, es una expresión de lo que sentimos por dentro: una gratitud profunda por ser llamadas por Dios y amadas por Él. Esa alegría brota de sabernos suyas, de saber que nuestra vocación es un regalo.

Para nosotras, Jesús en la Eucaristía lo es todo. Él es quien nos guía, quien nos ama y nos da fuerza. La misa, la adoración, y todo lo que rodea al Santísimo Sacramento es el centro de nuestra vida. Es el alimento que nos nutre el alma y el corazón.

Tenemos un cariño muy especial por la Virgen María. Ella es nuestra Madre, nuestra guía y nuestro refugio. En especial, reconocemos a la Virgen de Guadalupe como nuestra patrona. A Ella le confiamos nuestros sueños, nuestras misiones y la conversión de las almas.

Nuestra forma de ser misioneras no siempre es viajando o predicando con palabras. Muchas veces nuestra misión es rezar, ofrecer sacrificios y estar disponibles para ayudar en la conversión de los corazones. A través de la oración y el servicio, buscamos acercar a las personas al amor de Dios.

Sentimos que Jesús nos invita a seguirlo muy de cerca, como lo hizo en su vida pública, entregándose completamente a los demás. Nosotras también queremos vivir así: dándonos sin reservas y agradeciendo la oportunidad de ofrecer nuestra vida por amor, igual que lo hizo Él. Queremos ser una especie de “ofrenda viva”, unidas a Jesús Sacerdote, para el bien de todos.
