"The Christian must not be lukewarm. Revelation tells us that this is the greatest danger for a Christian: not that he says no, but a very tepid yes. This tepidness really discredits Christianity. Faith must become in us the flame of love, flame that really ignites my being, becomes the great passion of my being, and so ignites my neighbor. This is the way of evangelization...that truth becomes charity in me and charity like fire ignites my neighbor." (Pope Benedict XVI, Opening Remarks, Synod of Bishops on the New Evangelization)
