Baptism of the dead by proxy is what is being discussed in that passage, sorry for any confusion. The practice implies that the salvation of the dead can be affected by the actions of the living, ie: that there is a second chance, and so citing that passage in support of purgatory implies the same, that the disposition of those presumably held in that state or place is not certain.
Thanks RC. I don’t see baptism by proxy in this passage. It seems to be mostly making the point that the dead here are neither in Heaven nor Hell, so there must be somewhere else.
If we infer a second baptism or baptism OF the dead, this is not Catholic practice. If we believe it implies that those in Purgatory are not of the elect bound for heaven, this is incorrect Catholic teaching:
“The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned.”
