No marriage solemnized before a person professing to be a justice of the peace or minister of the gospel shall be void, nor shall its validity be affected on account of want of jurisdiction or authority in such supposed justice or minister, or on account of any omission or informality in the certificate of intention of marriage, if the marriage is in other respects lawful and has been consummated with the belief on the part of either of the parties thereto that they were lawfully married.
