They are humans just like us, at least in the flesh we think. For their way of life has a certain peculiarity, their behaviour different from ours.
They are detested because they cannot be emulated by people who cannot make the singular sacrifice of leaving behind vain pleasures of the world they live in.
But within them is the purest heart, sinless and bursting with love, not the erotic type most movies portray but that which Christ Himself showed.
Our world, choked with hate and deceit, needs more of love and peace, so we should always welcome and try to imitate them, these saints among us.
