The holy council declares, moreover, that the custom that this sublime and venerable sacrament be celebrated with special veneration and solemnity every year on a fixed festival day, and that it be borne reverently and with honor in processions through the streets and public places, was very piously and religiously introduced into the Church of God. For it is most reasonable that some days be set aside as holy on which all Christians may with special and unusual demonstration testify that their minds are grateful to and mindful of their common Lord and Redeemer for so ineffable and truly divine a favor whereby the victory and triumph of His death are shown forth. And thus indeed did it behoove the victorious truth to celebrate a triumph over falsehood and heresy, that in the sight of so much splendor and in the midst of so great joy of the universal Church, her enemies may either vanish weakened and broken, or, overcome with shame and confounded, may at length repent.
– Council of Trent, Session XIII, ch. 5
Our local parish is going to have a Corpus Christi procession. I hope nobody vanishes weakened and broken, but a bit of repentance here and there would be great.
