An equal-to-the-apostles (, isapóstolos; ; , motsikultastsori; ; , ravnoapostol'nyj; Bulgarian and Serbian: , ravnoapostolni) is a special title given to some saints in Eastern Orthodoxy. It is also used by Eastern Rite Catholic Churches that are in communion with Rome. The title is bestowed as a recognition of these saints' outstanding service in the spreading and assertion of Christianity, comparable to that of the original apostles.
