I am primarily a student of Western Esoteric texts, for example the work of Alice Bailey, Helena Roerich, Helena Petrovna Blavatsky, and Benjamin Creme, and also eastern Advaita texts. I have a little experience with studies of gnostic texts and the Bible.
Readers of this forum may already be familiar with the work of Benjamin Creme and his take on the second coming, but for those of you not already familiar, it is essentially a very hopeful view.
It is felt in this group that when Christ returns, he will not come to condemn anyone, but to reestablish the Kingdom of Heaven on Earth (or rather to re-establish it in our awareness, since it has always been here). That Kingdom belongs essentially to all - Hindu, Buddhist, Christian and Atheist alike, when they participate in it, with Awareness.
Awareness will prove to us the existence of God, the fact of mankind's identity as sons of God, and mankind and Christ's presence on earth as a servant of the Lord. I am putting this in Christian terms, but of course it is beyond all that. Christ comes to restore the sense (mainly forgotten) that mankind is One - even as it maintains its cultural, religious, ethnic and political diversity. Christ himself is expected in all these traditions under different names. The religions and political structures, or "isms", though they will persist, cannot lead to salvation in and of themselves.
For example, in Christianity, the formula "Only through Christ" has been misused to condemn others, and to put forward religion as the answer - however that begs the question, Who existed before religion? Ask yourself that question seriously, and you will come to the conclusion as I did that Christ and God both pre-exist their mention in any religious book, scripture, or any human manifestation. I would submit that Awareness existed before anything, and Awareness itself is the only Son of God - the first thing that emerged in the beginning, as it is said in first John. "In the beginning was the Word". This Word or Logos was always understood by the ancients (particularly the Vedanta or Advaita Hindus) to mean something greater than a text or person, though a person or text could be a relatively perfect manifestation of it as Christ in Jesus was.
This brings new meaning and a new perspective to the central pillars of Christian thought - the centrality of the Word and the person of Christ as the gateway to salvation. Both can be used to save, or, as is more commonly the case, to veil and hide the truth which is beyond words.
So I submit these ideas to you as nothing new, but something to consider with an open mind. Mr. Creme's website and magazine (entitled Share International - a google search will bring them up) are a trove of information on this vision of the second coming. A good distillation of Christ's first teachings in the modern era can be found in the book "Maitreya's Teachings - the Laws of Life" which were transcribed from talks He gave in the Brick Lane community between 1988 and 1993. These talks were attended by a member of that community and translated into English, and given to the editors of Share International. Mr. Creme's website has a couple of free books available as well.
