Doesn't Christ say in Matthew that He made them male and female since the beginning referring to Adam and Eve? And didn't the early church fathers and apostles believe that Genesis was literal history.
There is a tradition of calling things that are not as though they are. It begins with the yearly Passover celebration in which parents are ordered to tell children that they have escaped from Egypt. Its not a lie but a type of learning. Jesus is part of this tradition. Christians, similarly, are dead yet live in Christ. We regard ourselves as dead. Its not a lie, but its living in a different world. We're in the world but not of the world. Do you understand?
No, and the early church fathers are largely unknown except that they are originally pagan bishops who convert. One later church father, Augustine, says that the Genesis account is not literal. It matters not, because the fact is in a logical sense none of us are either slaves in Egypt nor dead with Christ on the cross except in faith. In faith we were dead in sin. In faith we are alive through Christ. Similarly in faith we eat the fruit of the tree of knowledge of good and evil. The creationists come to churches to shore up the ministries of men desperate to keep control of the congregations. That's my opinion. I am pointing out creationists are not faithfully representing anything: neither Science nor Christ -- in order to uphold my point to you that your OP is not really about agnosticism versus Christianity. Its certainly valid to raise your questions about many churches which insist on physical creationism.
No I think it just points out God's creative hand
Your profile and OP indicates that you are agnostic, but I think what you actually seem like to me is a little of both agnostic and modern Christian owing to a very physical view of God. All I want to point out is that there is not a dichotomy between believing in a physical God versus agnosticism. Agnosticism and atheism are both modern terms made necessary due to the transformations of Christianity away from its philosophical underpinnings in the post reformation period.
I think creationists do believe that God is only spirit and that everyone has equal access to Him. Why do you believe these things?
We disagree. Creationists believe God physically created the world and can be proven to exist through physical means -- through science, through miracles and through complex arguments about Bible verses starting with the arbitrary assumption of a perfect Bible straight from heaven favoring Christians over other people. One biblical author says "God is no respecter of persons," but a physical God is and also one that favors Christians.
Didn't it appear with actions of people singing and adoring God?
A physical God? No. They adore a God that is invisible and nonphysical and which exists in everyone. In addition the LORD is a covenant that is an expression of God much like the Bible is an expression of God or a person is an expression of God or the Holy Spirit is an expression of God, but creationists won't tell you this. They don't have a clue about it so far in my experience. How does a person adore God if not by treating others mercifully, doing justly and walking humbly? They may sing to the LORD, but that singing must be a commitment to a life of peace and waiting upon the LORD. To these people who are oppressed and frequently overrun by enemies, their singing to the LORD is truly a sacrifice not just a game or a pleasant noise. Its not like the adoration of Krishna. Its a purposeful, intensive, creative act, a promise.
I think you would be better served asking someone who is familiar with the development of the word 'God' than just anyone you meet on the internet. My view in a nutshell is that God is the rejection of gods, not very far from an agnostic position at all.
