Do we need to confess our sins daily?
If we really cared without condition, why wouldn't we?
However, we are all sinners (regardless of what you think this means)... Therefore it is incumbent on us to remember our trespasses (even on a daily basis), even if the Gospels do not mandate this.
Nicely put.
The bible says an eye for an eye and a tooth for a tooth, and the bible is referring to the idea of burning off bad karma.
Not really. Someone does something bad, you do something equally bad in return. That's too bad things. There's no good there, except the human sense of satisfaction that the suffering of another somehow cancels mine out.
In the New Testament however, we have a higher insight:
You have heard that it hath been said, An eye for an eye, and a tooth for a tooth. But I say to you not to resist evil..." (Matthew 5:38-39)
An interesting commentary on the doctrine of karma, in that Our Lord sees it as a perpetuation of evil. In fact He goes on at some length about the need to overcome the desire for revenge, which is basically how I see karma to be. A tribal practice wrapped into cultic practice.
I would also note that Our Lord does not say 'turn the other cheek ... let go thy cloak him ... with him other two (miles) ... Give ... turn not away ... Love your enemies ... do good to them that hate you ... and pray for them that persecute and calumniate you ... That you may be the children of your Father who is in heaven, who maketh his sun to rise upon the good, and bad, and raineth upon the just and the unjust."
This last point strikes out 'karma' as expressed, because it if were true, then heaven would make it rain on the bad guys, the sun shine on the good ...
I would also point out that we are not called to do this out of a sense of guilt. All this discussion about guilt and how we reject it comes across like excuses for not making the effort but assuming heaven is obliged to us just because we exist.
Radarmark had it right: We all sin because we none of us are perfect.
But since the dawn of time, in my Book anyway, we've been making excuses, finding fault, blaming our neighbour, or blaming God, for our own faults. Or worse, insisting on some kind of Panglossian utopia ...
