“the Feast of the Assumption?”
What even is that?
An assumption is a conclusion not based on evidence or facts and is presumptive.
A feast is well . . a big meal. A banquet.
Now when Catholics combine these two events together . . well that means Marys body and soul went to heaven. How did they get that? I don't know. Why would anybody worry if Mary is in heaven rather than Adam, Noah, Job or even the Apostle Paul? Well . . . that's why they call it a cult. We're really supposed to worry about our own soul and not anybody elses. John 21:20,21, 22.
