My kids attend a Christian high school and recently had an interesting (and difficult) assignment in one their Bible classes. I thought I'd share with you all and see what you come up with. (Don't worry, you are not helping them -- they've already turned in their work.) Part One - list five verses about God the Father, five verses about the Son and five verses about the Holy Spirit. Part two - from those 15 verses, develop the doctrine of the Trinity.
