Is it possible to be spiritual and not religious and still be Christian?

The question I seem to come back to: who cares? In the context of the practice of religion where we often seem to slice the pie in half: spiritual and religious, one wonders even we know what the words mean. The archbishop of Chicago, Francis Cardinal George, wrote about this topic in his column for Easter in the Catholic New World. The Cardinal outlines the issue pretty well: religion is becoming an isolated affair (some use the word private but I think it is better to say isolated since many families rarely talk about transcendent things with each other), that a question of authority disappears when you "when you make it up as you go along" and what it means to say there is an objectivity of what is true, beautiful, good and one is no longer easy to hold as a given. What exactly is religion?  Not to mention, many of our friends are now saying that the faith community as less and less credibility and the community of faith is trite. The missing element here is that Christianity is not about a set of rules, it is about a person; the practice of religion is not about the worship of myself, but the worship of a personal God revealed through the biblical narrative and seen in the sacraments; Christianity's truth is weak unless it is about conversion, vocation and mission made manifest in the life we share with others. As Cardinal Geroge said,

Meeting the risen Christ spiritually therefore depends upon believing in him religiously. We are given the gift of faith in the sacrament of Baptism, in which we are configured to the risen Christ. Faith perdures, even when there's not a lot of spiritual tingle in our lives! "Lord, I believe; help my unbelief," is the cry of a religious person who asks Christ to take him beyond his own spiritual experience into a new world where bodies as well as minds share in God's grace. Faith takes seriously everything that comes from God. The faith-filled person is sure of God and distrustful of himself. Unlike faith in God, experience is often wrong in religious matters.

Here is the full text of Cardinal George's "Easter 2013: I'm spiritual but not religious."

In short, it is impossible to call oneself Christian and not be honestly engaged in the weekly practice of worship with the faith community and worthily receive the sacraments.
