The history of the Mixcoac community began when the Pastor of Mascota, Jalisco, Father José Ramírez, requested a foundation for that city. With the approval of the Bishop of Tepic, Nayarit, His excellence Andrés Segura, and the consent of the Chapter Vicar, Msgr. Antonio Gordillo, he visited the convent of the Religious of the Incarnate Word in Guadalajara, where Mother Marie Claire of Jesus Dubois was the Superior.

In fulfillment of the promise made by the Incarnate Word to Mother de Matel, that His Order would be extended throughout all the world, and seeing in this foundation the fulfillment of this prophecy, the Superior called for a meeting to choose the Sisters who would go to this new foundation. Father José Ramírez presided over the election as a Delegate of Bishop Andrés Segura y Domínguez.

On Thursday, August 29, 1912, this group of Sisters began their long journey towards MASCOTA, JAL, accompanied by their Superior, M. Marie Claire of Jesús. They first arrived in America; from here the group continued on horse-back, through a very difficult, mountainous road, and after two days they arrived in Mascota, their "LITTLE BETHLEHEM" where they were very well welcomed by the people of the town. The house had signs of real poverty. On Sunday, September 1, 1912, Father José Ramírez blessed the house and the cloister was established.

Father José María Robles Hurtado (martyr for the faith), and Mr. Juán Robles Guzman, uncle and brother respectively of one of the Congregations first Mothers, took responsibility for providing what was needed to begin the community's apostolate, which began on October 8th of the same year. The Robles Guzmán family supplied provisions and fabrics, since they were owners of a great warehouse.

In December of that same year, 1912, Bishop Andrés Segura sent from Rome the DECREES OF FOUNDATION, expressing his satisfaction with the new religious community. Later on, he made the first canonical visit and celebrated Mass; and the Professed Sisters renewed their vows. Besides, he offered some financial help to meet the needs of the Community. The Sisters thanked the Incarnate Word for for so many favors.

As gold is purified in the melting pot and iron is forged on the anvil of the blacksmith, in the same manner the Incarnate Word wished to test the love and fidelity of the ones who would be the columns of the Community of Mixcoac, D. F.

On July 28, 1914, the revolutionaries entered the school to use it as headquarters for their sacrilegious activities. For that reason the sisters were forced to look for refuge among the families who were willing to offer them shelter, risking even their own security. This Revolution brought about the closing of many convents, causing the exodus of many young Sisters to their families or to migrate to places far from the revolution.

Another test that the Incarnate Word wanted to prove the love of his daughters was the death of their beloved Bishop, Andrés Segura y Domínguez, a great protector of the Community. His death took place on August 13, 1918.

On September 18th of the same year, 1918, in the México City, D.F., after a life full of sacrifice and virtue, the soul of Mother Marie Claire de Jesus Dubois was delivered to her Creator. She was buried in the French Cemetery of La Piedad. Years later, her remains were exhumed and taken to the Generalate of Chapalita, Jalisco where they remain today.

As a result of the Revolution and Religious Persecution, no community was allowed to receive new candidates nor celebrate any religious ceremony. This situation motivated the Superior, Mother Teresa Cruz, to request from the new Bishop of Tepic, Nayarit, Msgr. Manuel Aspeitia y Palomar, permission to move the community to a city without so much repression.

Once receiving the permission requested, and after eight years of permanence in that dear city of Mascota, the Sisters began their pilgrimage through different states of México. After two days of an arduous journey, they reached Guadalajara. From there, they continued to San Andres Tuxtla, Veracruz, where Bishop Plascencio received the sisters gladly, and urged them to remain in a house he had already prepared. Due to different circumstances, their stay in that place did not last very long.

They continued their pilgrimage, now to the city of Puebla, where His Excellence, Bishop Enrique Sánchez, suggested that the Community go to Teziutlán where they would be able to open a school. The Superior remained in Puebla with the Novices, so that the Novices could prepare themselves to make their Religious Profession; which they celebrated in the Convent of the "Religious of the Cross," on May 22, 1921. The Godmother of these happy professed was Señora Concepción Cabrera de Armida. The following day, with the Bishop's blessing, they left for Teziutlán to join our Sisters who were waiting for them with open arms.

In 1926, Religious Persecution broke out anew and the school was closed; this forced the Sisters to take refuge in private homes.

The Archbishop of Puebla, Msgr. Pedro Vera, seeing that it was impossible for them to return to reopen the school, asked the Sisters to transfer to Puebla, where they suffered inconveniences and poverty. In order to support themselves they decided to sell relics and cookies.

In 1930, during the time that the Community was in Teziutlán, the Sisters had the opportunity to meet Msgr. Agustín de la Cueva, who insisted that the Community should move to México City. He himself, took the necessary steps to obtain the permission from both Bishops: Msgr. Pedro Vera y Zuria of Puebla and Msgr. Pascual Díaz of México City. He also looked for a house where the Sisters could live; and found one on the corner of Yucatán and Zacatecas Streets, in the Colonia Roma. He also found the necessary furniture to open a school immediately, and to arrange all the necessary papers for the incorporation of the school into the SEP, the Public Office of the Secretary of Education. The school was named "Colegio Roma." Thanks to the good will and effort of these good people, the school grew rapidly and the Community was able to save enough money to buy the land where it stands today.
