An ordained person has been officially chosen and accepted for a special role, often in a religious or spiritual sense. This can also mean that something has been planned or decided in advance.
When people talk about being ordained, they usually mean that someone has been chosen to be a minister, priest, or other kind of spiritual leader. This is often after studying and training in their faith tradition. Sometimes the word is used more broadly for any person who has been formally recognized as having an important role within their community or organization.
It's worth noting that "ordained" can also have related meanings depending on its use in a sentence. For example, if you're talking about something being ordained by law, it means that it's officially allowed or approved.
To prearrange unalterably.
Established by authority.
