Some Christian congregations have rules about marriage. If the marriage is done according to the rules of the religion, it is sacramental. All other marriages are non-sacramental.
The pastor is the official witness of a sacramental marriage, with his permission, an assistant priest, or a deacon may witness it instead.

Catholics do not recognize non-catholic marriages as blessed or sacramental. Which sounds bad, but no other churches besides the Anglicans, Catholics, and Orthodox consider marriage a sacrament anyway.
The length of a marriage depends entirely upon the commitment of the man and woman involved. Marriages may last just a matter of hours, or they can last 75 years if both partners live long enough.
