Cardinal Ratzinger 50 year ago

From the crisis of today the Church of tomorrow will emerge — a Church that has lost much. She will become small and will have to start afresh more or less from the beginning. She will no longer be able to inhabit many of the edifices she built in prosperity. As the number of her adherents diminishes, so it will lose many of her social privileges. […) But in all of the changes at which one might guess, the Church will find her essence afresh and with full conviction in that which was always at her centre:  

faith in the triune God, in Jesus Christ, the Son of God made man, in the presence of the Spirit until the end of the world. In faith and prayer she will again recognize the sacraments as the worship of God and not as a subject for liturgical scholarship. The Church will be a more spiritual Church, not presuming upon a political mandate, flirting as little with the Left as with the Right. It will be hard going for the Church, for the process of crystallization and clarification will cost her much valuable energy. It will make her poor and cause her to become the Church of the meek. The process will be all the more arduous, for sectarian narrow-mindedness as well as pompous self-will will have to be shed.
