Gnosticism

Salvation by secret knowledge, in a cosmos where spirit is good and matter evil

Gnosticism names a family of early movements that taught salvation through secret knowledge and a sharp dualism dividing good spirit from evil matter. Associated with teachers such as Valentinus and Basilides, it was opposed by Irenaeus, whose Against Heresies catalogued and refuted it. The early Church rejected Gnosticism broadly, insisting that the material creation is good and that salvation comes through Christ rather than through hidden esoteric knowledge.
