God created man (male and female) in his image.
Were he to stop Eve from being able to think about and choose the fruit for its seeming benefit, he would have changed his mind - “I made man in my image, but now I am going to take my image away so she does not sin”.
So, you have either an eternal and unchanging God, or a God who himself changes his intentions in time, and therefore would be a contingent being himself.
It is God’s plan to have “fellow beings like him” to enjoy each other’s goodness, that they share his goodness. It could not be with angels, who upon creation know all they know and either turned to him or faced away into themselves. But it could be true with humans, who actualize their knowing in time, actualize their self-understanding in time, and come to know all things (including themselves) from material experience rather than from spiritual apprehension, as is with the angels.
This allows God to present himself to them not in his compelling being, but in other creatures materially present to them, so that they can come to desire and unite with God without violence to their being. Be clear, it was not “GOD” walking in the garden calling to them, but his Angel, having taken on a human form, who called “Where are you?”
Then at the right time, God himself, taking on human flesh, presents himself to be desired for union of love, a form that we can love because he is “like us”. And when we seek to join with him (“Might I be your disciple? Will you baptize me?”) he acquiesces, and joins to us, but fully, giving us divinity, his Spirit unites to us, so that now we are capable of loving the Majestic Divinity without the shock and awe that would kill us - we have become sons of God, loving our Father, and are like him.
Man was, you might say, “doomed to fall”. Without union with God, without infused Sanctifying Grace, man could not face God. And to give this grace to man “non-violently” it meant coming to man in a material presence that man could desire and seek. Before Jesus, men had this material union via promises / covenant, and in expectation - they desired to join to the promised Messiah, the seed of the woman. Since his Christmas, we do seek him and are granted union with him plus receive his Spirit and cry out, “Abba, Father”.
As for Moses, my Bishop and Pastor and Pope tell me he is the genuine prophet and that the others are not. Faith is assenting to what SOMEONE tells you, assenting to that SOMEONE who tells you something. Faith is not trusting some person-less idea. Moses is not the true prophet because ABC News says he is a prophet. He is nobody if the News says so. But he is the prophet because my Bishop, Pastor, and Pope tell me. He is your prophet if you are united in allegiance to the people who tell you that he is. In the same way, the Bible is Holy Scripture because my Bishop, Pastor, and Pope tell me it is so. It is not Holy Scripture sitting by itself in a bookstore, but only when a person is told so by someone with authority to speak for God gives it to you as Holy Scripture. The Ethiopian eunuch, reading the Prophet Isaiah, was not “happy” until Philip came along and “gave him the Scriptures” (explained), and baptized the Ethiopian. Then he went away singing - he was now a part of the people of the Scriptures rather than reading a foreign book that looked good. It was now his Scripture, and Isaiah was now his Prophet. Someone with authority gave the Prophet to him, and his new life of union with the Christ.
