Traditional theology has managed to redefine sin as rejection of the church. The Jewish law was burdensome, but the church has managed to one up Moses. If we don't attend church we are sinners; if we don't tithe we are cheating God. If we don't honor and follow church leaders, we reject God's divine guidance. If we don't pound the church's theology into our neighbors, we probably aren't real Christians. Instead of the message being about our relationship with God, it appears to be more about our subjection to the institution of religion.
I, for one, look for a redefinition of sin, one that puts the church and its definition in the necessary but superseded past. Moses and
Seeing humanity as woe-begotten lawbreakers instead of a collective of spiritually evolving children, simply implies that God has failed in His purpose, unless failure was the purpose. How can I fail without God failing?
As long as we focus our attention on overt behaviors as the evidence of sin and ignore the issues of state of mind, i.e. the lack of fruits of the spirit, we will miss the point of Jesus. We have 2000 years of church history to illustrate it.
Despite the lack of interest in the institutional church, the world is ripe, as always, for a real transformative message. Jesus had it, but somehow we have yet to see it clearly enough to allow its power to infuse our lives. Declining church attendance doesn't mark the end of the world, but the end of the beginning of a promised awakening.
