Question

why is discipleship the key to sharing in the "priesthood of Christ"?​

Answer 1

Answer:

A priest is In persona Christi, because he acts as Christ and as God. An extended term, In persona Christi capitis, “in the person of Christ the head,” was introduced by the bishops of the Vatican Council II in the Decree on the Ministry and Live of Priests, Presbyterorum Ordinis, December 7, 1965.
