I think that in some senses, all wrong acts need to be seen as the same. When we attach differing weights of severity to different deeds, we end up making different classes of morality. For example, a pedophile is seen as more morally deplorable than a man who cheats on his wife is. I’ll admit that I think this way all the time; however, I believe that this frame of thinking blocks a relationship with God.
The most fundamental step in Christianity is to recognize how flawed you truly are, and then to turn to God as a response to that awareness. But what if I believe in my heart that I’m not as flawed as others are? For example, say that I am a chronic liar, but that my neighbour cheats on his wife. If I start thinking that infidelity is a more detestable act that lying is, then I will soon begin to think that my neighbour is a more detestable person than I am. Thus, if I only see myself as half as flawed as my neighbour, then I’m probably only going to turn to God with half of my heart, if at all.
Examples of this type of thinking can be found all over the New Testament. Who were a lot of the people that responded to Jesus? Quite a few of them were prostitutes and tax collectors; people seen as the moral bottom-feeders of their society. They knew how flawed they were. And who were the ones who most vehemently opposed Jesus and everything that he was teaching? They were religious leaders; people who probably saw themselves as sitting atop the pyramid in the moral hierarchy. They had trouble believing that they were flawed, because they saw themselves as better than everyone else. Since they didn’t see themselves as being equally vile as the prostitutes and tax collectors, the religious leaders implicitly were saying that they didn’t need as much forgiveness as the prostitutes and tax collectors did.
So where am I going with all of this? I think that creating relative levels of wrongness for certain acts and behaviours will separate me from God. In fact, I don’t honestly think that I can call myself a Christian unless I can look into the eyes of a murderer, a rapist, or a pedophile and sincerely believe in the bottom of my heart that I am just as repulsive as he or she is.
