Contra the Papist position that makes God seem hormonal, continually sealing and unsealing, we believe God is true to his promises to what has been accomplished (justification) and what will be accomplished (sanctification). Contra to your supposed self-proclaimed knowledge, you don't have a clue about the Catholic position, as usual. We don't believe in a "[continual] sealing and unsealing". May I suggest a reading of the Catechism?
