I am the door, John 10:9

The teaching: "I am the door, John 10:9"; has a relationship with John 1: "In the beginning was the Word, and the Word was with God, and the Word was God". Jesus personifies the door, the door means the word of God, the wisdom of God. Every road starts with a door.
The path of Rectitude starts with the wisdom of God, with the word of God, the science of the divine. In the old and new testament the word of God is identified with the head of science and the intelligence: "For the lord gives wisdom: from his mouth come knowledge and understanding", Proverbs 2:6
The concept of Word of God does not match with the Aristotelian concept of Wisdom (Book of Metaphysics). The Word of God is in direct relationship with the faculties of the spirit: the intuition and the inspiration; 1 Corinthians 2:13 :"This is what we speak, not in words taught us by human wisdom but in words taught by the spirit"
Thomas Aquinas explains and this is important that the Bible is not the word of God, the bible is a book inspired by the word of God, by the counsel of God, because the Word of God predates the existance of man, the Word of God is eternal, is increated. Remember the expression in the Genesis that is similar to John 1.

The Wise

To understand what is a wise man, we have to study the metaphysical concepts of essence and substance. The essence is the main characteristic of the being. Example: the essence of man is reason, the essence of God is wisdom. The substance is that of what is preach. For example: when we talk about God, what we talk about? We talk about wisdom, the wisdom is the substance of God. When we talk about men? what we talk about? We talk about the person. The person is the substance of man. In Metaphysics there is similarity when there is participation in the essence. Man and God have different essences, there is no likeness between man and God. And this is where the idea of the wise arises, a wise is a person with the essence of God: the wisdom. The wise is by his essence the bridge between men and the divine. Aristotle in his book, "Politics" explains that the good government depends of the leadership of the wise men and in the succession from a wise to another the quality of life in the community.
