In the letter he issued on 28 August 2013, Cardinal Njue explained what we should expect during the Roman Phase:
“Once the Acts of the Diocesan Inquiry arrive at the Congregation of Causes of Saints, its officials will evaluate the validity of the work of our Archdiocesan Tribunal. If their work is favorably approved, the Postulator and Vice-postulator of the cause will then begin the writing of the Positio, an extensive biography of the Servant of God, under the supervision of a Vatican official. Once they complete the work, it will be studied first by theologians and then by cardinal and bishops of the Congregation of Causes of Saints. They will judge whether or not our beloved Cardinal Otunga had indeed led a heroic virtues during his lifetime.”
If the votes from both bodies are overwhelmingly positive, the Cardinal Prefect of the Congregation of Causes of Saints would present to the Pope a decree that recognizes that the Servant of God has practiced theological, cardinal and other virtues during his lifetime to a heroic degree. Once the Holy Father promulgates the decree, Cardinal Otunga would no longer be called “Servant of God” but would instead be called “Venerable”.
For a beatification to take place, it must be proven beyond doubt that an extraordinary miracle – that is, beyond scientific explanation – benefitted someone through the intercession of Cardinal Otunga. An alleged medical miracle must exhibit three characteristics: (1) the illness is of such a grave nature that there is no known cure for it; (2) the presumed cure took place in an instantaneous manner; and (3) the presumed cure is irreversible and the illness does not recur.
Currently, the Postulator and Vice-Postulator are meticulously studying several reported miracles wrought through the intercession of Cardinal Otunga. If one of them doubtlessly meet the aforementioned criteria, they will request the bishop of the diocese where the alleged miracle took place to open a Diocesan Inquiry and appoint members of the Tribunal that would investigate it. Once this work is done, the Acts will be sent to the Congregation of Causes of Saints. Once there, the findings will be scrutinized by the Congregation’s Medical Board, and evaluated by theologians and bishops and cardinals affiliated to the Congregation of Causes of Saints. If all of them are favorable toward the alleged miracle, the pope will issue a decree recognizing that the extraordinary miracle was indeed brought about through the intercession of the Servant of God. Shortly after, a date will be set for the beatification of Venerable. According to recent norms, this beatification will take place in the diocese where the life and virtues were investigated – thus, in our cause, in the Archdiocese of Nairobi.
Another miracle would have to be found after the beatification so that he could be declared. It must be of the same extraordinary nature and it would have to go once again through the aforementioned process. However, once the miracle is ascertained through a papal decree, the date of the canonization of the Blessed will be determined. As he would now be a saint of the Universal Church, the canonization would take place in Rome.
