I don't believe there is an official Church position.

In other words, no cut and paste answer to automatically believe because it has 'Dogma' stamped on it. If there were any scripture, you wouldn't have this mess. But there is none and scripture rules out the possibility of a purgatory. Therefore, you'll have to wait on them to find a way to draft it in philosophical arguments and hope they know what they are talking about. If it sounds right, they'll try it on the masses, it then becomes tradition and if people believe it, it must be right. Enter the Clergy to stamp it official and make it dogma, then it's all clear because it has an official stamp and somebody buys it. God can give you answers all day long. Why can't the RCC?
