In fact, the Psalter is the Old Testament book most frequently referenced by Jesus and the most cited in the New Testament. Christ and the Evangelists, along with Saints Peter and Paul, show a deep attachment to the Book of Psalms. This was not because the Psalms seemed to them to cover the full range of human emotions – a psalm for every mood. Not at all. It was not sentimentalism or anthropocentrism. Rather, it was because the Psalms were about the Messiah, the Christ of God. They were an esteemed, prophetic book about the Messiah Himself.
