Should I pray to learn the name of my guardian angel?

The practice of naming guardian angels is discouraged by the Church: “Popular devotion to the holy angels, which is legitimate and good, can, however, also give rise to possible deviations . . . [such as the] practice of assigning names to the holy angels [which] should be discouraged, except in the cases of Gabriel, Raphael, and Michael whose names are contained in Holy Scripture” (Directory on Popular Piety and the Liturgy 217).
