Ahh... Ok once again I fail to see how that has anything to do with a baby shower. Christ is simply telling us that He will save those who recognize that they are sinners not self righteous pharisees.
Since the Bible does not address baby showers (or indeed many specific situations) directly, we can infer the proper behavior in all situations by following similar examples of situations that are in the Bible. Really, what you are talking about here is cutting ties of fellowship with an individual. I think the Bible does setup very clear guidelines for how we are to treat one another:
1. Love others as you love yourself.
The Bible also talks in depth about the procedure for cutting someone off from fellowship. First go to them, if they won't listen bring a witness, if they won't listen bring the elders, if they won't listen cut off fellowship.
Apart from this proceedure, there is no precedence for "limited fellowship" ie - you fellowship with them, but don't throw a baby shower for them.
Its the church's responsibility to clearly declare the gospel. That involves telling people they are sinners.
Telling someone they are sinning, and establishing a punishment for that sin are quite different. If you throw baby showers for everyone except for the persons you deem "not moral enough", then you are judge, jurry, and executioner... as it were... in punishing that person for their sin.
Again why do you have to have a shower or party to show love. Are their not other ways to show love?
There are other ways... and you should be doing those ALSO. But taking away a loving act to punish for sin is not Agape love - unconditional love. If we follow God's model, we extend love while people are yet in sin.
Rom 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Why would she think that. The policy that was stated sounded like they would help the unmarried mother, but they did not throw the party for her.
If they throw parties for everyone else, and have not formally cut off fellowship with her, then they should throw her a party also.
Secondly since when do we have to make sinners "feel welcome" in church whether it be through a shower or some other gimmick. Just give them the gospel and let the Holy Spirit draw them to Christ.
Oh that's right... I forgot.... we're only supposed to love others once they have agreed to our statement of faith and signed off on their submission to the church's by-laws.
