It seems to me that one of the greatest aspects of the fall was the nature of the relationship between Adam and Eve. While Eve was deceived by Satan, Adam was not; he voluntarily ate that which was forbidden. I’ve wondered if that was not partly due to the Adam’s love for Eve and his desire to share life with her. A loving husband does not want there to be strife in his relationship with his wife. For Adam to hold his ground after Eve had already consumed the forbidden fruit would have caused great strife between Adam and Eve. By taking of the fruit, Adam may have thought something like, “Though it is forbidden, it is the lesser of two evils. I will at least maintain my relationship with Eve by joining in eating this meal.” Pure conjecture, but that’s how I see it.
It seems to me that this might also be the thought behind Paul’s mandate that we not share a meal with those who have claimed to be Christians, but have rejected Christ by their lifestyle.
ESV 1 Corinthians 5:11 But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler- not even to eat with such a one.The breaking of bread with someone who claims to be brother (in intimate relation) will affect the way we act towards them and will have an effect on our own actions. We will want so desperately to maintain the bond of peace. It will cloud our thinking as to the seriousness of the sin, as it may have done with Adam.
Then too, the culmination of God’s revealed plan is the supping with our Savior. When all is completed and we have been finally vindicated, we will sit down at the marriage supper of the lamb. We will enjoy that most intimate relationship with our Savior. He will be in us and we will eat with him.
