Stephen Hoeller, the modern day gnostic philosopher and Bishop of the Ecclesia Gnostica, put together a fantastic lexicon concerning the How's and Why's of gnosticism.
(Pay careful attention to number thirteen as it concerns "lay gnosis.")
Here is what he has to say concerning gnosis and salvation:
1. What is Gnosis?
Gnosis is the revelatory and salvific knowledge of who we were, of what we have become, of where we were, of wherein we have been thrown, of whereto we are hastening, of what we are being freed, of what birth really is, and of what rebirth really is. This is an ancient definition which is still accurate.
2. Is there more than one kind of Gnosis?
The experience of Gnosis comes to human beings in individual manifestations, yet it always has common features and a common keynote.
3. Is Gnosis an experience or a doctrine?
It is both. The experience of Gnosis is mystical knowledge that liberates. This is both accompanied and preceded by a kindred kind of Gnosis that informs. These were called (by Clement of Alexandria) the Divine Gnosis and Human Gnosis respectively. The human or doctrinal part of Gnosis consists of a certain kind of knowledge of the spiritual, psychic and material worlds and their relationships.
4. How is Human Gnosis acquired?
Primarily by way of the study and assimilation of the teachings of the Messengers of Light and of the seers and sages of the Gnostic tradition and by way of the amplification of these by individual insight.
5. How does one come to Divine Gnosis?
By divine grace combined with sincere and informed human aspiration.
6. What specific help is there available to us in order to receive both Divine and Human Gnosis?
Such help comes to us from Messengers of Light and other enlightened teachers of Gnosis.
7. Was there a time when humans were without Gnosis?
From the beginning of the human race, some people were in possession of Gnosis. These early Gnostics were at times symbolically called the "Great Race of Seth", after Seth, the third son of Adam, who was recognized as the prototype of all Gnostics.
8. Who was the latest great revealer of Gnosis?
It was the Lord Jesus Christ, who acted both as the rectifier of the existing tradition of Gnosis and as the revealer of new elements of Gnosis.
9. Can Gnosis be given by another?
A Messenger of Light comes to enlighten humans by his teachings and to transform their spiritual lives by the mysteries he bestows on them. But only those in whom the true spiritual intuition ("the Light Mind") is awakened will welcome the message and benefit from the mysteries.
10. What are we to be saved from?
We are to be saved first from ignorance which prevents us from knowing our true source, our real nature, our condition and our destiny. At last we shall also be saved from the burden of earthly existence with its attendant conditions of suffering and exile from our true home.
11. What brings about salvation?
Salvation is brought about neither by faith (belief in God, or Christ) nor by works (the performance of good deeds), but by Gnosis.
12. Why is this so?
Because faith and works do not result in a radical change in the being of one's consciousness, but Gnosis does.
13. What does the radical change of consciousness brought about by Gnosis accomplish?
It establishes a renewed link of the soul with the spirit and of both with God. This breaks the bonds that have shackled our true being to the forces of earth. Ultimately it brings liberation from all earthly things.
14. What are the further benefits of salvation by Gnosis?
A turning away of the soul from the attachments of life, a constant straining upwards to the pure Divine Spirit, wherein is our true home. Also, God's friendship in this life, a good death, and after that a swift passage through cleansing regions to God's presence in the Fullness (PLEROMA) of divine glory, goodness and love.
