What is a Spiritual Father?

If the best doctors help to heal our physical bodies by knowing the "right" medicine, so even more does the spiritual father, who is enlightened by God, prescribe the much-needed healing for our soul. “It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners to repentance." This is the path to purification, and one does not accomplish it on his own. The Church is our hospital offering the healing medicines of Holy Confession, the Holy Eucharist, and Holy Unction. Without the Church, we are easily mislead into wrong "treatments" prescribing ourselves pain killers when we might need a spiritual heart transplant!!! (Mark 2:17 or Matthew 9:11-13, Luke 5:31)
