Homiletical theory suggests that the genre of a text should determine how it is preached. When it comes to the Psalms that bit of advice poses a problem for me. Since I’m not a poet, trying to write a poetic sermon might not work all that well. But, even if you’re not a poet, it is good to regularly visit the Psalms. That’s because they speak powerfully about God and God’s creation. So, in the coming weeks most of my sermons will draw from the Psalms. However, I do want to put your minds at ease. I won’t be writing any bad poetry to share with you!
The Sunday after Pentecost is known as Trinity Sunday. It’s on this day in the church year that we focus our attention on the nature of God. From a theological point of view, the doctrine of the Trinity is a good reminder that God transcends our attempts to define God’s nature. When we look to the Psalms for guidance on such matters there is a Latin phrase that captures the essence of this: Lex orandi, lex credendi. This translates in English to “the law of prayer is the law of belief.”
The hymns and prayers that we find in the Book of Psalms can lift up our hearts to God in praise and thanksgiving. They also give us the words to share our laments and our complaints. Anyone who says that you can’t argue with God has never read the Psalms!
