How many times may a man be ordained?

A man can be ordained multiple times, but typically, the Catholic Church recognizes ordination as a sacrament that can only be received once. This means that a priest who has been validly ordained cannot be ordained again, as the sacrament imprints an indelible spiritual mark. However, in some cases, a man may receive different orders (e.g., deacon, priest, bishop) within the same sacramental framework, but each ordination is considered distinct and final.
