Thanks for the clarification. In LDS policy, you can’t be disciplined/excommunicated if you resign. Of course, the process of resignation, as is common among big organizations, have to go through processing that may take a certain length of time, especially since the Church is comprised of volunteer workers.
This is really nothing different than the Roman Catholic “Defectio ab Ecclesia catholica actu formali”.
The LDS Resignation works the same way as the Roman Catholic Defectio in that your name is not removed/scrubbed from the Roman Catholic church register. It is merely annotated with the Defectio declaration as it is necessary in the administration of the Church. Both LDS Resignation and Catholic Defectio also work the same way in that the member is effectively separated from the Church, not just in a juridical manner but a true schism from the life and blessings of the Church.
In addition, LDS Resignation also works the same way as the Catholic Defectio in that the baptismal covenant is a permanent bond with the Body of Christ and is not rendered non-binding by defection.
And finally, LDS Resignation works the same way as the Catholic Defectio in that it requires a formal written letter that has to go up the organizational structure and requires some time to be processed.
Hope this helps.
