The transformative nature of baptismal gifts in death are that faith and hope are replaced with sight and possession, and that peace is the fruit of divine love.
What then is purgatory?
I think that maybe it comes from the lack of a complete peace because our sight and possession is not yet wholesome or fully transformed. Perhaps in the acts of life and the act of death, we retain fear and we possess what is not from God. I wonder if sometimes it comes from the fear of losing that possession that is not from God and that our hopes are not yet entirely placed in Him, or more specifically His will.
There is an act of justice in the sufferings of purgatory, for what is the work of justice if not the work of peace? The restorative powers of justice have the same goal as the object of our hope, the tranquility of order, completeness and perfection, the peace of Christ.
Baptism for us is like the Word made a seed and planted in us; and confirmation is like when a seed containing life makes first contact with water, that it might sprout and grow into fullness. However, a seed must stop being a seed to be a plant. A fruit must no longer remain attached to a plant to be useful to the one who buried the seed. Purgatory is for us who are not picked first, but when we let go of our roots to the earth, we might find our way still to the banquet in one basket or another.
The Lord will take us at His will. Lord, make me an instrument of your peace.
