John 16:12-13
I have much more to tell you, but you cannot bear it
now. But when he comes, the Spirit of truth, he will
guide you to all truth.
Acts 1:8
But you will receive power when the holy Spirit comes
upon you, and you will be my witnesses in Jerusalem,
throughout Judea and Samaria, and to the ends of the
earth.
Catholic Christians believe
that Christ's teaching authority and
truth charism continues in
His Body the Church in the successors
both of Peter and then the
apostles, and then to their successors:
the successor of Peter in the Bishop of Rome,
and the
successors of the apostles,
the episcopoi or bishops from
apostolic time to the present.
