That day may one day come, but a priest should prioritize Scripture and Catechism over private devotions at all times - especially when he is a guest in someone else's parish.
Unless he pridefully believes that he is given a greater faculty of spiritual discernment than the Church in these matters, he would do best to stick with the publicly proclaimed teaching of the Church and not the private teaching of individuals.
I would be appreciative if you could offer me some web sites regarding your statement “Gloria Polo’s claims are private revelations that have not received positive approbation from the Magisterium.”
Also if you could indicate a few web sites which might explain the proper interpretation of the decree of the “Sacred Congregation for the Doctrine and the Faith”, published in the “Official Acts of the Holy See” (A.A.S.) 58/16, dated December 29, 1966 (”The Canons of the Catholic Church About Private Revelation”).
Thank you
