Cheon Il Guk

Korean: 天一國 (天 cheon — heaven/heavens; 一 il — one; 國 guk — nation/kingdom)

Also known as: The Nation of Cosmic Peace and Unity; The Kingdom of Heaven on Earth and in Heaven; God's Homeland

Definition

Cheon Il Guk is a central concept in the teachings of Sun Myung Moon, referring to the ideal nation — or kingdom — of God, in which all of humanity lives united under God's true love. It represents the fulfillment of God's original purpose of creation: the establishment of a world where God, humankind, and all creation dwell together in complete harmony, without sin or division.

The term is composed of the Chinese characters 天 (cheon, heaven), 一 (il, one), and 國 (guk, nation). Rev. Moon explains that the character 天 (heaven) can itself be broken down as 二人 — "two people" — signifying that Cheon Il Guk is fundamentally the nation where two people become one: husband and wife, subject and object, heaven and earth, mind and body.

"Cheon Il Guk is the nation where two people become one. Heaven must hold those two people... Where two things, two people, two parents, two characters — subject and object partners — become one, a foothold for God is created."
— Sun Myung Moon (370-88, 02/19/2002)

Etymology and Meaning

Breaking down the name reveals layers of theological meaning:

天 (Cheon) = Heaven / the heavens. When divided by stroke: 二 (two) + 人 (people) = two people becoming one
一 (Il) = One / unity / oneness
國 (Guk) = Nation / kingdom / country

The full phrase 天宙平和統一國 (Cheonju Pyeonghwa Tongil Guk) — "Nation of Cosmic Peace and Unity" — is the formal extended name. In common usage, the abbreviated form Cheon Il Guk is standard.

Three Pillars: Sovereignty, Territory, and Citizenry

According to Rev. Moon's teaching, a nation requires three foundational elements, all of which Cheon Il Guk must possess:

Sovereignty — restored through the Coronation Ceremony for God's Kingship (January 13, 2001)
Territory — restored through the Rallies for the Settlement of God's Fatherland
Citizenry — established through the registration of Blessed Families as citizens of Cheon Il Guk

"The Nation of Cosmic Peace and Unity (Cheon Il Guk) needs sovereignty, territory and citizenry... That is why you must have the Cheon Il Guk identity cards in order to be its citizens."
— Sun Myung Moon (364-87, 01/01/2002)

Conditions for Becoming a Citizen of Cheon Il Guk

Cheon Il Guk as Original Homeland

In Rev. Moon's teaching, Cheon Il Guk is not a foreign or future place — it is humanity's original homeland, lost through the Fall of Man and now being restored. Every person's birthplace is meant to become part of this heavenly hometown through the work of Tribal Messiahs and the blessing of lineages.

"Human history has emerged out of the dark night into the dawn to greet the new bright sun... Humanity's hometown — the original homeland — cannot emerge without the emergence of these parents."
— Sun Myung Moon (16-258, 06/19/1966)
