I challenge the assertion that Christianity is any more rationally based than other religions. It is not quite as mystical as say Buddhism or as esoteric as Daoism, for example, or eve Judaic Cabalism. But it certainly requires a suspension Reason in favor of Faith to believe in principles like the Holy Trinity, the Eternal Life, and even the Soul.
Not that that is a bad thing. Religions exist to answer questions for which there are no answers. Ultimately, ALL of them demand some element of Faith.
God doesn’t exist because I can prove He does; He either exists or He doesn’t. So the question becomes less “Does He exist?” than “Do you BELIEVE that He exists?” And that belief, that Faith, owes nothing to Reason. Nor should it.
You don’t need to reject reason to believe in Christianity.
You do (however) have to reject reason to believe in - for instance - Islam, as their ‘god’ is arbitrary and incoherent.
