[quote=sententia]If a catholic and a non catholic (NOT baptized) person are married, this marriage can be blessed but is NOT sacremental?
If a catholic and a non-catholic (baptized christian) are married this can be sacremental.
Assume everything is done through the Church as whatnot
A Catholic / non-Baptized marriage is not a Sacramental Marriage but a natural Marriage and is a true Marriage and indissoluble. If the Bishop grants a dispensation for the Catholic to enter Marriage with a non-Baptized person. Otherwise Canon Law says that the Marriage is invalid. Yes an invalid Marriage can be Convalidated after any impediments are removed and the necessary permissions and dispensations are granted.
It also becomes Sacramental at the moment the non-Baptized person receives valid Baptism.
A valid Marriage between a Catholic and a Baptized non-Catholic is always Sacramental.
