One of the most beautiful symbols of Christianity depicts the Cross next to a pelican injuring its side in order to feed its little ones from its blood. Each one of us is in a way or another a shepherd of some sort. The older brother cares for his younger brothers and sisters, and the father carries great responsibilities. The Christian employer sees his work as a service for others, and his employees as being his younger brothers. Every profession or work or any position in life is vain unless it contains some kind of service or care.
Love ought to be the purpose and nature of every relationship in daily work.
Thus care is the expected result. The feast of the Three Hierarchs is a perfect example. The most important, noble and delicate mission and service is the science of theology and priesthood. The example of the three hierarchs proves to us that the sign of the true theology is good care to the flock. So, the essence of pastoral care is theology.
