Correct - it is not at all associated with any sacrament (unless one considered the ongoing life we live in faith, during the course of which we come to receive the Eucharist, absolution, and any other sacraments that might apply to our lives). But no, they are not linked as a one-time dependent event.
(Of course, we are just discussing theologies and sharing. And that's where "defensible" applies. But the important thing my mind goes back to, is that I certainly can't imagine God nit-picking over such details as a reason to "invalidate" anyone's salvation. So ... while I'm interested in learning, that's where my focus goes.
And that prevents me having much more to say about something I'm not familiar with. Thank you for explaining!)
