As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
Dogmatism & Ignorance
When Jesus asked his opponents whose son the Messiah was (Matthew 22:34-46) they answered with orthodox dogmatism, correct but ignorant of Christ. When churches spoon feed us with ready made answers that leave out thinking, they do us disservice. They do not allow us to love God with our minds. What thinking formed the teachings of the Church? Good theology schools teach the various views of doctrines along with strengths and weaknesses of each view. One professor taught that doctrine was a 2,000 year long discussion and that discussion is not over yet. Too often we approach church doctrine as if there is no more discussion. We dare not use our minds. Jesus’ challenge to his opponents was to use their minds. If the Messiah is the son of David, how could David refer to him as Lord?
