The only thing that concerns me about the Ark recreation and the young earth theory is that a few of the people that I know and go to church with that fully believe it, are so adamant about it that one in particular throws out sayings such as: "if you don't believe that the Creation event happened in 6 literal days, what other parts of the Bible do you not believe?" It's that type of "my way" thinking that drives wedges between believers. IMO, there is no place for that in Christianity. There's already a dump truck full of wedges that get driven between believers of different denominations, we don't need more. Like you, my faith isn't based on the Creation event, it's based on the Cross.
Fur, I want you to hear me saying this with a humorous tone of voice (I'm not jabbing at you), but that's what I call "Rodney King Christianity"....can't we all just get along? It isn't a matter of getting along, or I think what I want to say is I will subordinate getting along to being doctrinally sound. Guys, there are some things that are mysteries, and some things that aren't. The creation account is NOT a mystery, it isn't even remotely a debatable topic, and that's why this is such a big deal. There has never been a reason FROM SCRIPTURE for any man to even think it meant something other than a literal single day. This debate is ALWAYS and ONLY an attack on scripture, and (if I make no other point ever again on this site) you do not know God or His gospel without scripture. If it's common to twist the portion of scripture regarding the creation, then what makes you think you don't believe a twisted understanding of "the gospel"? Things that are mysteries are things that aren't in scripture. For example, what does Jesus look like? Should we do contemporary or traditional music? See where I'm going? It's not about the dogma of my opinion, it's very much like Martin Luther risking his very life to correct the theology of the mainstream church in that day. Actual scriptural accounts aren't matters of opinion, they are matters of theology, and (like I've been saying) a lack of theology will be the indictment of our generation. If it takes me (lovingly) disagreeing with others to defend scripture, then I must do so. Doctrine does divide, it's intent is to do so (like a two edged sword). Scripture is as clear about the literal 6-day creation as it is that we no longer need a mediator priest.
You know, oddly, I am far more tolerant of someone who is confident about wrong theology than I am someone who doesn't believe it matters. And I really bristle at the "there are just some things we can't know" remark. This usually comes from that person who just isn't interested in theology. There are innumerable answers in scripture, but we are so theology-averse today that we wouldn't know otherwise.
