All great questions of life have only one answer. Conflicting and contradictory answers cannot be valid. Jesus’ unique claim for himself while answering Thomas (Jn. 14:6) is a statement which is philosophically and logically reasonable. Even those who deny unique and exclusive approaches to truth would insist that their own approach is unique and exclusive! Otherwise, they would have nothing to say! Truth, by definition, is therefore exclusive and narrow. It has to exclude errors in order to qualify to be truth.
It is a surprise to many people to discover that there are only a handful of passages in the Bible that directly mention homosexuality.
