I have asked my local bishop to have all the parishes restore the St. Michael Prayer after all Masses. We need to call on St. Michael. I have not heard from the Bishop and wonder what I can do to see this practice restored.
Your desire to pray this prayer is understandable, and good. The prayer can in fact be said. However, perhaps a little history and context is appropriate to understand why it fell away in the early 1970s.
Historically, the liturgical movement beginning in the 1940s and continuing through the Second Vatican Council., sought to reemphasize the Eucharistic liturgy, by distinguishing it from some of the devotions that had grown up around it. The hope was to emphasize participation in the Mass as the greatest devotion.
Among the devotions that attached themselves were a number of prayers said following the dismissal from Mass. Thus, although the priest turned and said Ite Missa est (Go the mass is ended), this was not exactly so. First there was a blessing, then a recitation of the last Gospel, and then after most masses, prayers, which included the prayer to Saint Michael. In many parishes Benediction of the Blessed Sacrament was also done.
Liturgists of the time sensed that lesser devotions following the greatest devotion somehow implied an inadequacy in the prayer of holy Mass.
Whether or not you agree with all these points, it was the thinking at the time, which led to the elimination of many, if not all, devotions immediately following the Mass.
That said, you and fellow parishioners, are not forbidden from praying certain prayers and devotions following mass, even with the priest. It is best however, to allow those who need to depart, e.g. for work, to leave prior to the beginning of devotions. Otherwise, people feel trapped, and the instruction that they may go, is lost or reduced in meaning.
Please also be aware, while the St. Michael Prayer is an important prayer, many others also insist on other devotions for similar reasons. Thus some pastors are reticent in fostering such public devotions, since requests tend to multiply. So pastoral discretion is needed, and solutions will vary from parish to parish.
