A scientist examines natural phenomenon with great attention and we, with greater attention, should examine the phenomenons and the actions of the grace of God. Behold, what one of the great spiritual fathers' witnesses about the act of Holy Communion. Father John of Kronstadt writes: "I am amazed at the greatness and the life-giving power of divine Communion. An elderly woman, who was spitting blood and was so completely exhausted from not being able to eat anything, began to recover the day that she received Communion from me. A young girl close to death began to recover, eat, drink and speak after Communion whereas, before that, she was unconscious, in convulsions and did not eat or drink anything." O, if every priest, with the attention of a scientist and with the love of a prayerful man, did observe and follow the actions of the Grace of Holy Communion similar to Father John!
