The Gospel for the Seventh Sunday after Trinity is from St. Mark 8:1-9. This is one of several gospel accounts of feeding the multitudes (there is similar account in St. Mark 6). In addition to the miracle itself which is a manifestation of Christ's divine power over nature, the story of Christ feeding the 4000 shows us several things about our Lord's earthly mission. It shows Christ's compassion toward the physical hunger of crowds (8:2). In addition, the setting of this particular feeding is in a Gentile area near Galilee. This fact implies that Christ's compassion extends to all sorts and conditions of humanity.
Furthermore, the context shows that our Lord has a deep concern for spiritual hunger. The people that He feeds physically are those who hunger for His words, His spiritual nourishment. They are people who have followed Jesus out into the countryside and listened to His teachings for three days. They are physically hungry because in the words of the Sermon on the Mount, they "hunger and thirst after righteousness" (Matthew 5:6). So here we see Christ's special mercy for those who seek to follow Him.
Besides telling us about Christ's earthly ministry, our Gospel also teaches us about the continuing mission of the Church. 1) Like our Lord, we should manifest compassion for the basic physical needs of human beings, such as hunger. 2) Christian concern for both physical and spiritual needs is universal. That is, compassion extends to all people. Although compassion is most often expressed in our everyday human contacts, it must extend to anyone that we meet who has a physical or spiritual need.
3) This compassion for human hunger also has spiritual dimensions. Indeed, while it may be less obvious, spiritual hunger is a deeper need. Human beings are designed for fellowship with God. Even when people are not aware of its existence, there is a spiritual hunger in every soul which can only be supplied by Jesus Christ. As Christians, we are all called to point others to Christ who continues to nourish human souls through His Word and His Sacraments.
