Being Christians, we know that the future is ours and the tree of the Church is not a tree that is dying but a tree that constantly puts out new shoots. Therefore we have a reason not to let ourselves be upset, as Pope John said, by the prophets of doom who say: well, the Church is a tree that grew from the mustard seed, grew for two thousand years, now she has time behind her, it is now time for her to die. No. The Church is ever renewed, she is always reborn. The future belongs to us. Of course, there is a false optimism and a false pessimism. A false pessimism tells us that the epoch of Christianity is over. No: it is beginning again! The false optimism was the post-Council optimism, when convents closed, seminaries closed and they said “but... nothing, everything is fine!”.... No! Everything is not fine. There are also serious, dangerous omissions and we have to recognize with healthy realism that in this way things are not all right, it is not all right when errors are made. However, we must also be certain at the same time that if, here and there, the Church is dying because of the sins of men and women, because of their non-belief, at the same time she is reborn. The future really belongs to God: this is the great certainty of our life, the great, true optimism that we know. The Church is the tree of God that lives for ever and bears within her eternity and the true inheritance: eternal life.

[Pope Benedict at the Roman Seminary, 8 February 2013]
