Christianity is inextricably bound up with the notion of sin. The Bible tells the story of the triune God’s rescue mission to redeem rebels out of their sin and guilt, which alienates them from his shared life of light and love. The gospel of Jesus Christ is the central message of how the Son came in the power of the Spirit to conquer sin and death through his own life, death, and resurrection. Without seriously considering the weight of sin, as Anselm so famously urged us to do, we can’t possibly understand the glory, goodness, and mercy of God’s liberation. Neither can we respond to it appropriately with repentance, faith, and worship. This is why Christians have historically spent so much time talking about sin.
If you’ve been around church long enough, though, you know there are plenty of ways to “talk about sin” that fall short of considering its full weight. I can think of at least five.

Well summarized Derek. This is me repenting.
Perhaps another way to fool ourselves is to think that we can talk comprehensively about sin. For we see one of two faults in the above ways of talking about sin. One fault is that the talk about sin is correct but is incomplete and/or has errors. The other way is that the talk about sin totally wrong. Regarding the above ways, I would classify the sectarian way as the only way listed above which has no merit. For all it accomplishes is the externalization of evil and thus it puts us and our the groups we belong to into the role of the Pharisee from the parable of the two men praying.
The other ways listed above of talking about sin has merit and can be placed in conjunction with the other ways of talking about sin. The youth group way has the merit of talking about sin in relation to how we compare with others. The Millennial way has the advantage of recognizing the effects of previous sins and how they affect our lives today. The Mainline way recognizes the corporate sins committed by the groups to which we belong. This way of recognizing sin is overlooked most often by my fellow religiously conservative Christians. The evangelical way forgets how we sin against others either as individuals or in groups, but it is valuable in terms of how we sin against God.
Thus, we should consider whether the 4 of 5 ways of looking at sin as described above are more incomplete than in error, though error is bound to happen when one’s views of sin are incomplete.
Does the Bible not tell us that there is only One True God, the God of Abraham of Whom no images may be made? Worshipping in front of images of gods or saints, bowing down in front of them and taking more than one god is an abomination in the eyes of God, and as such it is also considered a sin. Therefore we only should worship One True God and should not make His only begotten son into a god to be worshipped either.
