That's a reasonable conclusion from the evidence.
The Roman Catholics are johnny on the spot when it comes to incorporating pagan rituals/celebrations into their religion. Weird how it just seems to flow easily from one group to the next. Does anyone have any information on how many pagans rejected their former beliefs for Catholic beliefs once they joined the church? Or is it a Haiti/South American voodoo/catholic merging of convenience meant to satisfy all who enter? And no one has to reject anything, as long as Mass is performed and Eucharist is taken literally. Unity, you know...
That's a reasonable conclusion from the evidence.
