What is a spiritual father or an elder (starets), and why is it so important to have one?

The Orthodox nuance

The Desert Fathers speak much of a particular trap, called in tradition prelest or spiritual delusion — the moment when you believe you have advanced spiritually, when you have perhaps had a "vision" or a strong feeling, and in reality you are being led by pride disguised as piety. Saint John Climacus and Saint Symeon the New Theologian write about this emphatically, precisely because it is a subtle trap: the more convinced you are that you cannot be wrong, the closer you are to it. It is like wanting to see your own back without a mirror — you need someone else's eyes.

The custom of seeking a spiritual father is as old as monasticism itself; disciples went to the fathers of the Egyptian desert, like Saint Anthony the Great, and asked for "a word of profit," not a general formula, but advice tailored exactly to their struggle. This tradition flourished especially on Athos and in Russian monasticism, with fathers like Silouan the Athonite, Paisios the Athonite, or John of Kronstadt, men whom crowds sought precisely for a recognized gift of discernment, not because they advertised themselves.

You do not need to be a monk to have a spiritual father; every Orthodox Christian who takes their faith seriously is called to have one, someone they turn to — not one today and another tomorrow — so that a real relationship of trust can grow, in which the priest knows their struggle over the long term. Obedience in the spiritual life is not military or blind, it is earned; a good spiritual father does not steal your freedom, he helps you see clearly, sometimes precisely by refusing to decide for you, so that you learn discernment yourself. And in our time, with so many spiritual "influencers" on screen, it must be said clearly: a real spiritual father knows you in flesh and blood, over time, not through a few-minute clip.
