What is the apostolate about which we are talking? There is but a single apostolate, a single central purpose to the Church, to bring the Gospel to every person. Immediately before his Ascension, in what has been called his last will and testament, Christ said to his disciples, ‘Go into all the world and proclaim the good news to all creation’(Mk 16:15).
The knowledge of Christ and the call to personal sanctification are to be brought to all. When Christ said all, he meant all. The fruit of his Passion must not be wasted.
