On November 21, 1923, through the words of the founder, Fr. James Alberione: “Set aside Orsolina and Metilde”, began the period of preparation for the establishment of the  new family.  This had  already been preceded by the foundation of the Society of St. Paul and that of the Daughters of St. Paul.

A month later, on Christmas Eve of 1923, Fr. Alberione officially announced his intention to form a new group: “We have set aside Orsolina and Metilde in order to found a new family which will be dedicated to prayer, to the worship of the Divine Master in the Eucharist, to perpetual adoration in reparation for the sins committed through the bad press.  They will devote themselves to  a life of silence and recollection”.

On February 10, 1924, the Feast of St. Scholastica, the Congregation of the Sister Disciples of the Divine Master began with the first eight postulants.  Orsola was appointed as the person in charge of the group.  Together with the “Prima Maestra” Tecla Merlo they prepared secretly for the investiture.

On March 25 of the same year they held the investiture and professed their vows privately in the presence of the founder, Blessed James Alberione.  Orsola Rivata received the new name of Sr. Scholastica.  She was named after the sister of St. Benedict who was described as the woman who “was able to do much because she loved much”.  Mother Scholastica would fulfill the same role within the Pauline Family.

In the meantime, through the goodness of the Divine Master, the Congregation grew with the entrance of new members.  Mother Scholastica exercised her ministry of responsibility with great dedication, tact, attention toward those under her care.  Her responsibilities were primarily organizational and not juridical since the Sister Disciples were not juridically approved as yet.  She worked in the kitchen, the workroom and the garden as one among her sisters.
