We, the faithful, should look upon all the faithful as one single being, and should consider that Christ dwells in each of them. We should have such love for each of them that we are willing to lay down our lives for them. Nor should we ever think or say that anyone is evil: we should look on everyone as good, as I have already said. Even should you see someone overwhelmed by some passion, execrate, not him, but the passions that fight against him. And if he is mastered by desires and prepossessions, have even greater compassion for him; for you too may be tempted, subject as you are to the same fluctuations of beguiling materiality.
~St Symeon the New Theologian
