Odd how the Oriental Orthodox - including the Coptic Orthodox Church of Alexandria, the Syriac Orthodox Church, the Armenian Apostolic Church, the Ethiopian Orthodox Tewahedo Church, the Eritrean Orthodox Tewahedo Church and the Malankara Orthodox Syrian Church who separated in 451 - 1200 years before the Council of Trent - all have the same seven sacraments the Catholic Church has.

And the Orthodox Catholic Church, the second largest Christian church, separated since 1051 fully 500 years before the Council of Trent, have the same seven mysteries (sacraments).

I wonder how that happened?

Perhaps Trent, dealing with Protestant theories on the sacraments and their enumeration at zero, two, two major and five minor by various sects, wanted to clarify there were always seven, their divine origin, and their forms and matters?
