I think it is important, if we are going to speak about salvation, we must first define what it means to be "lost" or not "saved". I do believe the fundamentalist's approach has some merit in calling attention to humanity's "lost" condition and then offering salvation through a relationship to God through Christ. However, I think they are off base in their understanding of the Atonement of Christ and their concept of heaven and hell as some place or form of existence after death. So, I would disagree with someone who believes in a universal salvation because (1) I doubt there is any kind of "heaven" which exists to which all will arrive, and (2), I've seen too much evidence that many people do not have, but are desperate for, salvation.
I am also saddened, BeachOffEden, that your past in a fundamentalist sect has robbed you of an appreciation for the bread and wine that was cause for celebration and a source of power for the early church. If you have opportunity to read Oscar Cullmann's Early Christian Worship, I think you would find it profitable. But in the meantime, take a look again at the passage in 1 Cor. 11:17ff. In the context, what does Paul consider to be an "unworthy" eating and drinking? What was his concern? Wasn't it that there were divisions in their attempt to be community - the body of Christ? Some were hungry while others overindulged at the party to the extent that they became drunk. Taking the bread and wine unworthily doesn't seem to have any connection with some kind of personal piety, but a failure of some to have an inclusive love. Some failed to "recognize the body of Christ", which was the central purpose of coming together in the first place. The meal was the sign and sacrament at which the presence of the Risen Christ could be experienced in their relationship with one another.
So, rather than not taking the bread and wine because you feel unworthy, I think you should throw a party and celebrate with others the fact that we have access to a shared experience of God's life and power, and then, in an act of worship, while sharing food and drink with others, expect God to show up!
