Since people for some reason do not understand these concepts and continually misstate what they mean, I'm going to clarify:
http://www.religioustolerance.org/gnostic.htm
Gnosticism is a philosophical and religious movement which started in pre-Christian times.
The name is derived from the Greek word "gnosis" which literally means "knowledge." However, the English words "Insight" and "enlightenment" capture more of the meaning of "gnosis." It is pronounced with a silent "G" (NO-sis). Gnosticism is not factual, intellectual, rational knowledge, such as is involved in mathematics and physics; that would have been more accurately represented by the Greek world "
episteme."
Rather, Gnosticism involves the relational or experiential knowledge of God and of the divine or spiritual nature within us. A visitor to this web site wrote: "
...we believe that gnosis-knowledge requires ultimate transcendence of the merely intellectual to be actualized."

Gnostics believe that they have secret knowledge about God, humanity and the rest of the universe of which the general population was unaware. It became one of the three main belief systems within 1st century Christianity, and was noted for four factors by which differed from the two other branches of Christianity:

Novel beliefs about Gods, the Bible and the world which differed from those of other Christian groups.

Tolerance of different religious beliefs within and outside of Gnosticism.

Lack of discrimination against women. Although
Jesus treated women as equals, and Paul mostly did the same, the other Christian belief systems
started to oppress women in later generations.

A belief that
salvation is achieved through relational and experiential knowledge. In the words of
The contemporary Gnostic Apostolic Church, humanity needs to be awakened and brought "
to a realisation of his true nature. Mankind is moving towards the Omega Point, the Great day when all must graduate or fall. This day is also the Day of Judgment in that only those who have entered the Path of Transfiguration and are being reborn can return to the Treasury of Light."

The movement and its literature were essentially wiped out before the end of the 5th century
CE by Catholic heresy hunters and the Roman Army. Its beliefs are currently experiencing a rebirth throughout the world, triggered in part by the discovery of an ancient Gnostic library at Nag Hammadi, Egypt in the 1940s, and the finding of the
Gospel of Judas at El Minya, Egypt, in the 1970s.
Agnosticism:
Uncertainty about whether God exists
http://www.religioustolerance.org/agnostic.htm
The range of meanings of the term: "Agnostic:"
Agnosticism is a concept, not a full religion. It is a belief related to the existence or non-existence of God. However, many people have started with an Agnosticism, and have added a moral code, rituals and other items to create a belief system with many of the attributes of a religion. When asked what their religion is, many Agnostics will reply "Agnostic." Since so many Agnostics regard this as their religion, we have a policy of capitalizing the term out of respect, as we do for all religions on this web site. This is not often seen on the Internet, but we feel that it is appropriate.
Agnosticism implies uncertainty about the existence of God. The basic problem here is that there are many answers to the question "
Does God exist?" However there is only this one term available to cover all of the meanings. Some of today's possible overlapping answers to the question are:
- I don't personally know.
- I don't know but will lead my life in the assumption that no God exists.
- I don't know but will lead my life assuming that God does exist.
- I cannot give an opinion because there is no way that we can prove the existence or non-existence of God given currently available knowledge.
- I cannot give an opinion because there is no way to know, with certainty, anything about God, now and in the future.
- Yes, God exists. But we do not know anything about God at this time.
- Yes, God exists. But we have no possibility of knowing anything about God, now or in the future.
Ultimately, the term "
Agnostic" is something like "
Christianity." Both refer to a wide diversity of belief systems, but in many cases, an individual asserts that their particular definition is the only fully valid one.
The one principle linking all meanings of "Agnostic" is that God's existence can neither be proved nor disproved, on the basis of current evidence. Agnostics note that some theologians and philosophers have tried to to prove, for millennia, that God exists. Others have attempted to prove that God does not exist. Agnostics feel that neither side has convincingly succeeded at their task.
Evolution of the term "Agnostic" over time:
Three main meanings have been associated with "Agnostic" since Thomas H. Huxley invented the term in the mid-19th century
- Huxley defined agnosticism as follows: "... it is wrong for a man to say he is certain of the objective truth of a proposition unless he can provide evidence which logically justifies that certainty. This is what agnosticism asserts and in my opinion, is all that is essential to agnosticism." 11
- "... an agnostic is someone who not only is undecided concerning the existence of God, but who also thinks that the question of God’s existence is in principle unanswerable. We cannot know whether or not God exists, according to an agnostic, and should therefore neither believe nor disbelieve in him." 12
- An agnostic is undecided about whether or not God exists.
Are Agnostics also Atheists?
Agnostics are not Theists. Agnostics do not believe in a God, or a Goddess, or in multiple Gods, or multiple Goddesses or in a pantheon of Gods and Goddesses. However, some Agnostics consider themselves to be
Atheists. That is because the term "
Atheist" has two slightly different meanings:
1. A person who positively believes that no God(s) or Goddess(es) exists. E. Haldeman-Julius suggests that: "The atheist perceives that history, in every branch of science, in the plainly observable realities of life and in the processes of common sense there is no place for the picture of a God; the idea doesn't fit in with a calmly reasoned and realistic view of life. The atheist, therefore denies the assumptions of theism because they are mere assumptions and are not proved; whereas the contrary evidences, against the idea of theism, are overwhelming." 1
This is the definition of Atheism used by most Christians, other Theists, and dictionaries of the English language.
2. A person who has no belief in a God or Goddess. Just as a newborn has no concept of a deity, some adults also have no such belief. The term "Atheist" is derived from the Greek words "a" which means "without" and "Theos" which means "God." A person can be a non-Theist by simply lacking a belief in God without actively denying God's existence. This is the definition of Atheism used by many Atheists. They use the term "strong Atheist" to refer to a person who denies the existence of one or more deities.
Some Agnostics feel that their beliefs match the second definition, and thus consider themselves to be both Atheist and an Agnostic. Such confusion is common in the field of religion. We have found 17 definitions for the term "
Witch," eight for "
cult," and six for the "
Pagan." -- all different. A lack of clear, unambiguous definitions for religious terms is responsible for a great deal of confusion and hatred. It makes dialog among Agnostics, Theists, and Atheists very difficult. In fact, when such a dialogue is attempted, it should be preceded with a long session to resolve definitions.
As currently defined, an agnostic usually holds the question of the existence of God open, pending the arrival of more evidence. They are willing to change their belief if some solid evidence or logical proof is found in the future.
Further definitions:
George Smith, the author of "Atheism" divides agnostics into two types: - Agnostic theists: those who believe that a deity probably exists;
- Agnostic atheists: those who believe that it is very improbable that a deity exists. 5
Another category of Agnostic is "empirical Agnostics." They believe that God may exist, but that little or nothing can be known about him/her/it/them. Still another category are "Agnostic Humanists." These individuals are undecided about the existence of God. Further, they do not really consider the question to be particularly important. They have derived their moral and behavioral codes from secular considerations. Their ethical behavior would not be altered if a deity were proven to exist.Some agnostics who feel the need for religious discussion, fellowship, or ritual join a congregation of the Unitarian-Universalist Association or an Ethical Culture group.
Dictionary definitions of "Agnostic:"
- Houghton Mifflin: "One who believes that it is impossible to know whether there is a God. One who is skeptical about the existence of God but does not profess true atheism." 8
- Columbia encyclopedia: "[A belief] that the existence of God cannot be logically proved or disproved. Agnosticism is not to be confused with atheism which asserts that there is no God." 9
- Wikipedia: ['A belief] that the (truth) values of certain claims -- particularly theological claims regarding the existence of God, gods, or deities -- are unknown, inherently unknowable, or incoherent, and therefore, irrelevant to life." 10
- Merriam-Webster: "A person who holds the view that any ultimate reality (as God) is unknown and probably unknowable; broadly : one who is not committed to believing in either the existence or the nonexistence of God or a god." 13
- Die.net: "One who professes ignorance, or denies that we have any knowledge, save of phenomena; one who supports agnosticism, neither affirming nor denying the existence of a personal Deity, a future life, etc." 14
So, to sum up:
GNOSIS:
The name is derived from the Greek word "gnosis" which literally means "knowledge." However, the English words "Insight" and "enlightenment" capture more of the meaning of "gnosis." Gnosticism involves the relational or experiential knowledge of God and of the divine or spiritual nature within us.
AGNOSIS:
The one principle linking all meanings of "Agnostic" is that God's existence can neither be proved nor disproved, on the basis of current evidence. As currently defined, an agnostic usually holds the question of the existence of God open, pending the arrival of more evidence. They are willing to change their belief if some solid evidence or logical proof is found in the future.
