Question from Philip Lester on 04-02-2005:

How quickly will John Paul II arrive in heaven?

Answer by Colin B. Donovan, STL on 04-02-2005:

No one can say. He may already be there. My own opinion is that he is. If he is canonized in the future by a Pope, as I believe he will be, we will have our definitive answer. In the meantime, we pray for the repose of our soul, and we may privately pray to him, though not publicly.
