Palamism
Palamism or the Palamite theology refers to the teachings of Gregory Palamas (c.1296–1359), whose writings defended the Orthodox notion of Hesychasm against the attack of Barlaam. Followers of Palamas are sometimes referred to as Palamites.
Seeking to defend the assertion that humans can become like God through deification without compromising God's transcendence, Palamas distinguished between God's inaccessible essence and the energies through which he becomes known and enables to share his divine life. The central idea of the Palamite theology is a distinction between the divine essence and the divine energies that is not a merely conceptual distinction.
Palamism is a central element of Eastern Orthodox theology, being made into dogma in the Eastern Orthodox Church by the Hesychast councils.
Palamism has been described as representing "the deepest assimilation of the monastic and dogmatic traditions, combined with a repudiation of the philosophical notion of the exterior wisdom".
