What sins do the different Christian denominations agree on?

It is humorous how one Christian just posted her opinions on what you specifically asked is sin... and said none of it is sin. But other Christians will say that all are a sin, others will say one or two of the three are. There are also Gay/Lesbian Pastors or Preachers... so clearly even that one is not agreed upon.

None of the things you mention.

Some things that, as far as I know, are taught by all Christian sects to be sin:

- homosexual behavior

- any sex outside of marriage

- blaspheming God

- murder, theft, and in general "crime"

- war (yes, Christians teach that war is sin, but in cases of self-defense a necessary sin, and in that case the responsibility for the sin of war lies primarily with the instigator - that is, the party that first perpetrated violence against the other party)

as far as Lutherans Go there is the ELCA the LCMS and the WELS.

I only know what the ELCA and LCMS say,

THe ELCA is the most liberal and a none of those things would be a problem

THE LCMS official stance on tattoos and Working in Sunday is that is ok.

THE LCMS is not too cool about Divorce.

THe WELS is ULTRA COnservative.

No, they don't all agree. That is part of why there are different denominations.

sin is any thing against Gods wish I am sure we all agree on that. so lieing adultery murder lust and many more

the sin of unbelief which condemns sinners to hell

Sex is a huge sin. and people who have sex can't get tp heaven.
