I assume you are referring to the seven sacraments of Catholicism and the Orthodox Churches. The Catholics and Orthodox (which were a single Church until the twelth century, more or less), believe that the seven Sacraments were instituted by Jesus Christ Himself, in an early form, when He was on earth.
The seven sacraments are Baptism, Confession or Reconciliation, Eucharist (Communion), Confirmation, Holy Orders, Matrimony (Marriage), and Viaticum (Anointing of the Sick).
The pope is a priest and bishop and. as such, can administer all 7 sacraments.
Catholic & Orthodox follow the 7 Sacraments (though in Catholicism a person may only take at the most, 6 Sacraments). Protestants do not have all 7 Sacraments.

The Catholic and Orthodox churches recognize them still.
All of the sacraments allow believers to experience God's grace. When sins are confessed and forgiven, believers receive God's grace.
