I have been confronted on multiple occasions with a very anti-religious viewpoint. Maybe the most surprising encounters have come from those within the church and those sympathetic to Christianity. Let me explain further, there is a very real movement away from religious acts and toward spiritual being. While they are elements of Christianity (called sacraments) that I believe are necessary to practice regularly (by definition, religious), I have also found that there is a something to learn in this idea, and it relates to humility and sincerity.
Again, I am not advocating rejection of the sacraments, but I do believe that the church in America has too often attached a Pharisaical set of ideals, rules, and/or expectations to the gospel and thus presented a stumbling block.
A list of rules to follow so often leads to a sense of religious pride, the idea that by accomplishing that list, we are better than we were, or better than someone else. However, we know that the Law was given to us for the opposite reason. Law is to show us our utter insufficiency, not proficiency.
There are certainly principles of conduct that are divinely right and true - love, justice, purity, sincerity - to name a few. Jesus taught us that simple rules like "do not commit adultery" and "do not kill" are not enough for true obedience or conformation to God's character because when we lust or hate, we are guilty all the same.
So, what's my point? My point is that piety, adherence to religion, can lead to pride. Pride is the enemy of sincerity in our lives, and pride and piety (in this sense) undermine the gospel. To promote obedience as any kind of measure is to undermine the grace of Christ, the righteousness of Christ, the substitutionary sacrifice of Christ.
This, I believe, has led to the current sense of repulsion by many in America to religion and the move among Christians for spirituality. This is a cry for sincerity and humility.
Paul states of his ministry, "For we are not, like so many, peddlers of God’s word, but as men of sincerity, as commissioned by God, in the sight of God we speak in Christ."
A peddler has something that you can have for a price; we are ambassadors for one who offers a free gift. Those to whom we preach do not deserve the gift, and as "men of sincerity," we know that neither do we.
