via the Vatican:
A fire does not burn by itself; it has to be fed or else it dies; it turns into ashes. If everything continues as it was, if we spend our days content that “this is the way things have always been done”, then the gift vanishes, smothered by the ashes of fear and concern for defending the status quo. Yet “in no way can the Church restrict her pastoral work to the ‘ordinary maintenance’ of those who already know the Gospel of Christ. Missionary outreach is a clear sign of the maturity of an ecclesial community” (BENEDICT XVI, Apostolic Exhortation Verbum Domini, 95). For the Church is always on the move, always going out and never withdrawn into itself. Jesus did not come to bring a gentle evening breeze, but to light a fire on the earth….
The fire of God is warmth that attracts and gathers into unity. It is fed by sharing, not by profits. The fire that destroys, on the other hand, blazes up when people want to promote only their own ideas, form their own group, wipe out differences in the attempt to make everyone and everything uniform.
