Furthermore, the absolute fallen and sinful nature of mankind is THE MESSAGE OF THE BIBLE. The entire Old Testament is a representation of man's inability to save himself through his own perceptions of righteousness.
Romans 3:23 is a pivotal verse for evangelicals:
That verse, in a single sentence, sums up the very reason that Christ needed to come to earth and die on the cross. It is paramount to evangelicalism.For all have sinned and come short of the glory of God.
By disregarding their own sinfulness before God, and focusing only on the sinfulness of gays/lesbians, these believers bring themselves into condemnation by God.
Another key aspect of Christian thought is that only Christ is the judge. Someone could easily be a believer in Christ, and feel that they were made by Christ to be gay. Why does this club feel that only a fundamentalist interpretation of doctrine is allowable? If they want university sponsorship, that means that they have to be open to all people who state that they are Christians. Their choice to be so narrow in their interpretation.
