Sermon 7 marks a transition to a new area of debate: “whether the Son and the Father have the same power and might, whether they are of the same essence” (7). As mentioned previously, the Anomoeans were Arians so they denied that the Father and Son were consubstantial. Chrysostom has already been laying groundwork for his arguments in previous sermons, but now this subject gets his full attention.
The arguments of Chrysostom are pretty straight-forward; it is the same line of reasoning used by many today. Jesus has the same nature as the Father because he is begotten of the Father (8-10). Things begotten have the same nature as their begetter. Trees beget trees. Dogs beget dogs. Man begets man. God begets God. While Chrysostom will address objections of the Anomoeans, he does not address the problems inherent in our conception of begetting: namely, that something begotten must have a beginning.
The preacher does recognize a somewhat related argument however: Jesus is a son and so are we so there must not be any difference between us. Chrysostom responds that even though we are called sons of God, he is the only begotten Son. We are adopted, but he is begotten (11-12). Because Jesus is the only begotten, he shares in the glory and substance of the Father so Jesus says things like:
- Whoever has seen me has seen the Father. John 14:9
- I and the Father are one. John 10:30
- For as the Father raises the dead and gives them life, so also the Son gives life to whom he will. John 5:21
- that all may honor the Son, just as they honor the Father. John 5:23
- My Father is working until now, and I am working. John 5:17
Chrysostom anticipates the Scriptural objection his foes will raise: there are multiple passages that demonstrate the Son is lower than the Father. For example, the fact that the Son prays to the Father shows he does not have the same power (14-15). Chrysostom gives four main reasons for this phenomenon of Scripture.
First, the incarnation (16-17). Jesus had to demonstrate that he was true man. As a man Jesus was completely dependent upon the Father. If Christ did not demonstrate that he was true man, what hope could man have for his salvation?
Second, the inability of his hearers to comprehend the truth (18-26). This idea of Jesus’ condescension to his hearers is a destructive weapon in the hands of liberal critics of the Scripture, but Chrysostom handles it well. Over and over again, the foes and disciples of Jesus responded with wonder, anger, disgust, and revulsion to Jesus’ “more sublime words” (18). Had Christ simply appeared on the scene teaching and only taught the deeper spiritual truths about his identity, he would have quickly lost all hearers.
Third, to teach humility (27). As the preacher states,
If someone is teaching humility of heart, he does this not only by what he says but by what he does. He is moderate in both word and deed. Christ said: “Learn of me because I am meek and humble of heart.”
Fourth, to make clear that God is not a monad (28). The truth of the Trinity is multifaceted and incomprehensible. As has been said, try to understand it and you will lose your mind; deny it and you will lose your soul. Had Jesus only taught his unity with the Father, it would have been even easier to fall into the belief that there is only one person in God. Even with the mixed testimony of Scripture, Sabellius found enough to teach that the Father and Son are not two distinct persons. Without the teaching about Christ’s humility, it would be even easier to fall into this heresy.
The remainder of the sermon is devoted to a fuller explanation of how the incarnation “lowered” the Son to a place of prayer (34-54). For this, Chrysostom devotes his attention to the apostle John’s account of the last supper and Jesus’ prayer in the garden.
The sermon is concluded with another exhortation on prayer (55-64).
Surely, prayer is a harbor for those caught in a storm; it is an anchor for those tossed by the waves; it is a staff for those who stumble. Prayer is a treasure for the poor, security for the rich, a cure for the sick, a safeguard for those in good health. It keeps our blessing inviolable and quickly changes our ills to good. If temptation comes, it is easily repelled. If loss of possessions or any of the other things which cause grief to our souls befall us, prayer is quick to drive them all away. Prayer is a refuge from every sorrow, a basis for cheerfulness, a means for continual pleasure, a mother for our philosophy and way of life. (61)
