Is meaning of Christianity limited solely to that of the relationship of individuals to God? Perhaps the answer lies within the question whether God standards are set on an individual bases or for all of humanity? It would appear then disagreements of behaviors that some would consider un-Christian or even sinful may be argued as being Christian or non-sinful if the person justified the actions based on intra-personal relationship with God: lets for argument sake they truly feel or believe that a certain behavior that others view as unchristian or sinful is not according to what they perceive to be God's wishes. This would leave some holding an intra-personal believes that those same actions are unchristian or sinful. If meaning of Christianity lies within intra-personal relationships then does this mean God's intention is for us to learn to live together harmoniously despite these contradictions. If this is the case does this mean there is no such thing as unchristian or sinful behaviors?
