A Catholic man who has the required attributes and no obstacles in canon law, and intends to follow the charism of the Michaelites, may join the Community as a brother or as a priest.

Postulate: It can take place in every house of the Congregation and lasts for several weeks (for candidates for the priesthood) or for the half year (for candidates for the brothers). At that time, superiors will recognize the suitability of the candidate for the order, and the candidate will gain a preliminary knowledge of life within the congregation to which he will become part of.

Novitiate: This is the year of discernment of one's vocation, intensifying spirituality and making the decision. Novitiate ends with the profession of temporary vows of chastity, poverty and obedience. Currently novitiate for candidates takes place in Poland, Paraguay, and Papua New Guinea. It can also be initiated in any of our provinces, vice-provinces or delegations.

Seminary: Six to eight years of studying philosophy and theology. During the studies seminarians have a pastoral year in one of the parishes or  educational facilities. Culmination of this stage is ordination to the priesthood. Different provinces and vice-provinces offer opportunities for formation and studies in countries where Michaelites are present: Australia, Paraguay, Italy, Germany and Canada.
