All of the ones we know today were in practice, although the term ‘sacrament’ wasn’t really used until after the Edict of Thessalonika in 380, which made pagan religions illegal in the Roman Empire. Up until that point, ‘sacramentum’ was a Latin term which denoted the worship of the pagan mystery cults like the cults of Isis, Mithras, and Sol Invictus. Afterward, when Pagan sacraments would not be confused with Christian sacraments, it took a great deal of time (until the middle ages) until sacraments were readily identified as the seven we know today.
