Just found a good quote about the Catholic Church assimilating pagan practices (which is something I’m always on the lookout for):

“…the norms on inculturation given by Pope St Gregory the Great in a letter to priests written in 601:

It is said that the men of this nation are accustomed to sacrificing oxen. It is necessary that this custom be converted into a Christian rite. On the day of the dedication of the [pagan] temples thus changed into churches, and similarly for the festivals of the saints, whose relics will be placed there, you should allow them, as in the past, to build structures of foliage around these same churches. They shall bring to the churches their animals, and kill them, no longer as offerings to the devil, but for Christian banquets in name and honor of God, to whom after satiating themselves, they will give thanks. Only thus, by preserving for men some of the worldly joys, will you lead them thus more easily to relish the joys of the spirit.”
