Orthodoxy and dogmatic theology isn't the problem. They are necessary if you happen to believe that there is such a thing as truth and that it matters.
What makes you think the truth could be understood and worked out by human beings?
What if we don't have the imagination or knowledge to come up with the right answer?
That might be true if it were not the case that we have the Holy Spirit to guide the Church in such matters, as our Lord promised.
"But the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you"
"But when the Paraclete cometh, whom I will send you from the Father, the Spirit of truth, who proceedeth from the Father, he shall give testimony of me"
"But when he, the Spirit of truth, is come, he will teach you all truth"
