Sister Eugénie Joubert worked tirelessly as a catechist for children and young people, especially the poorest and most abandoned, in keeping with the spirit of the Congregation of the Holy Family of the Sacred Heart.
She went even further, devoting herself to a life of apostolate. She was above all interested in all those who, lacking any natural means, required a great deal of patience from her. Without tiring, she would repeat the essential demands of the catechism in a very simple way for children and young people. By dint of prayer and her interior life, Sister Eugénie Joubert loved to pass something of the fire of love that embraced her own into the hearts of the children she taught.
