"I still have more things to say to you, but you cannot bear them now." St. John
Glory be to the Father, and to the Son, and to the Holy Spirit. Amen.
John Calvin wrote: " God has never so blessed God's servants that they each possessed full and perfect knowledge of every part of their subect. God's puspose in limiting our knowledge was first that we should be kept humble, and also that we should continue to have a need for our brothers and sisters." (Romans commentary)
Calvin rightly reminds us that none of us can fully comprehend God and truth and belief. Contrary to Fundamentalists, you cannot encapsulate God or the Gospel in five or six fundamentals! I pity those who think they know everything about God or Jesus or who is saved or who is not, or who think in terms of fundamentals. When I was at Catholic University I was astounded at what Father Friday said one day in a class on Ethics. He was trying to loosen up the class made up by primarily priests and the nuns, as he said, "Listen, we can argue and debate in our church, we have the right to dissent. There are only two doctrines we cannot argue with and they have nothing to do with Jesus, but only with Mary - she was assumed into heaven, and she was immaculately conceived in her mother Anne's womb, besides that anything is up for debate." I was shocked, not about Mary mind you, but about the idea that in Catholicism you can debate and argue, that nothing is fully settled completely. That was refreshing!
In my humble opinion, and knowing the irony of my certainty here, those who think they are so certain are furthest from Christ. Jesus told stories to keep us all in suspense; these were open ended parables that kept us off the throne of judgment. Jesus knew how quickly we turn religion into a power trip of certainty and damnation and so he told stories where the hero was the enemy (parable of the Good Samaritan), or the field shouldn't be weeded (parable of the Weeds in the Field). or the younger wild brother gets the party and the good, righteous older brother pouts in the darkness (parable of the Prodigal Son). Jesus seems to say there is always more to say and think.
I think the church's belief in the Holy Blessed Trinity, of God experienced not as a strict monotheism but as three "persons," was its way of saying, there is always something more to say about God. There is always more to be revealed. The United Church of Christ's motto is "God is still speaking." And there is a lot of truth in that statement; revelation doesn't end. Christians, thus, have always been a tolerant faith, tolerating diversity, tolerating mystery, tolerating even dissent. Jesus says, "I have more to reveal to you." Isn't that a curious statement. You would have thought Jesus would have wanted to carefully define doctrine and nail things down, set six fundamentals we had to believe in, set up a school of theology, but he did not. He left it all opened ended. I think he was very wise, because human beings have a tendency to become very mean and are always playing God. He wanted the church, his followers always to remain humble, and always have a need for each other. Calvin was right. Wise teachers like Jesus, whom we claim to be God, says as God: "would ya'll keep your big mouth shut; you ain't God for Pete's sake; humbly speak in my name, and never forget how much you need each other."
