The essential matrix of New Age thinking is to be found in the esoteric-theosophical tradition which was fairly widely accepted in European intellectual circles in the 18th and 19th centuries. It was particularly strong in freemasonry, spiritualism, occultism and theosophy, which shared a kind of esoteric culture. …
New Age is not, properly speaking, a religion, but it is interested in what is called “divine”.
An adequate Christian discernment of New Age thought and practice cannot fail to recognize that, like second and third century gnosticism, it represents something of a compendium of positions that the Church has identified as heterodox. John Paul II warns with regard to the “return of ancient gnostic ideas under the guise of the so-called New Age : We cannot delude ourselves that this will lead toward a renewal of religion. It is only a new way of practising gnosticism – that attitude of the spirit that, in the name of a profound knowledge of God, results in distorting His Word and replacing it with purely human words. Gnosticism never completely abandoned the realm of Christianity. Instead, it has always existed side by side with Christianity, sometimes taking the shape of a philosophical movement, but more often assuming the characteristics of a religion or a para-religion in distinct, if not declared, conflict with all that is essentially Christian”.
