The dangers is that every religion, including the Catholic one, says "I have the ultimate truth." Then you start to rely on the priest, the mullah, the rabbi, or whoever, to be responsible for your acts. In fact, you are the only one who is responsible.
Man with his burning soul Has but an hour of breath To build a ship of Truth In which his soul may sail- Sail on the sea of death. For death takes toll Of beauty, courage, youth, Of all but Truth.
The nimble lie
Is like the second-hand upon a clock;
We see it fly; while the hour-hand of truth
Seems to stand still, and yet it moves unseen,
And wins, at last, for the clock will not strike
Till it has reached the goal.
Truth resides in every human heart, and one has to search for it there, and to be guided by truth as one sees it. But no one has a right to coerce others to act according to his own view of truth.
