In the Catholic Church there is mystery and certainty at the same time. One of the mistakes of the current time is to think that there are no certainties, no revelation that we can interpret with certainty, not so.
For Catholics, the Church is the community founded and run by Christ ('on this rock I will build my Church'). Our task isn't to create a new church, though I of course encourage the movement toward adoration and prayer to God, but to follow the Church that God has given to us as the instrument of salvation, of the fullness of life which starts even here in this life.
'The house for all sinners and saints' could be a name for the Catholic Church, everyone is welcome.
