You are equating Purgatory with Abraham’s Bosom, without giving any ECF or theologian support for it, when even the Catholic Encyclopedia states that Abraham’s Bosom is now synonymous with Heaven, with no mention of Purgatory at all.
You originally cited the Lazarus story as evidence of a “middle place” (then implied that this middle place was Purgatory in that post), when the Lazarus story is evidence of the existence of Abraham’s Bosom, not Purgatory.
You speculate on what actually happens/happened in Abraham’s Bosom (“cleansing”), when there is no basis for this, and again, without any theological citation.
You ignore that Purgatory includes a…purgatorial element that is absent from Abraham’s Bosom.
The Catechism of the Catholic Church gives two different views of Purgatory and Abraham’s Bosom.
I have already said that there is a similarity between the two, in that they are “middle places”. However, the existence of one place (Abraham’s Bosom) does not imply or necessitate the existence of another place (Purgatory). Therefore, bringing up Abraham’s Bosom in support of Purgatory doesn’t make sense, because Abraham’s Bosom is only proof of itself, as it has nothing to do with Purgatory. As Choy also said, it’s a [SIGN]completely different thing[/SIGN].
