Why believe when there are scandals?

Scandals cause real pain and must be taken with complete seriousness, through justice, reparation, and conversion. They must not be covered up or disguised with pious phrases. Yet Christian faith does not rest on the sinlessness of Christians, but on Christ. Precisely because sin exists, we need grace, truth, and a Church that returns time and again to her Lord. This question requires calm, not a quick slogan. Many doubts are understood much better when you separate things: what faith says, what reason can see, what comes from personal experience, and what perhaps arises from a wound or prejudice.
