as a catholic i beleive this is a purgatory even when Virgin Mary appeared to people she told them there is a purgatory. Purgatory is when your not bad but you still have some sins to pay off cause you are not cleaned to go to heaven and yet your sins aren’t bad to enter hell so after you paid your debt in purgatory you go to heaven. if your a catholic you have to beleive there a purgatory if not then your not a true catholic.
