Germanic paganism
The triquetra has been found on runestones in Northern Europe and on early Germanic coins. It presumably had pagan religious meaning and it bears a resemblance to the Valknut, a symbol associated with Odin.

Neopaganism
Modern Pagans use the triquetra to symbolize a variety of concepts and mythological figures.Germanic Neopagan groups who use the triquetra to symbolize their faith generally believe it is originally of Norse and Germanic origins. Due to its presence in insular Celtic art, Celtic Reconstructionist Pagans use the triquetra either to represent one of the various triplicities in their cosmology and theology (such as the tripartite division of the world into the realms of Land, Sea and Sky),or as a symbol of one of the specific triple Goddesses, for example, The Morrgan.

Wicca

The symbol is also sometimes used by Wiccans and some New Agers to symbolize either the Wiccan triple goddess, the interconnected parts of our existence (Mind, Body, and Soul). Also the triquetra is a symbol of protection in the Wiccan religion.

One of the most occultic television shows ever aired is Charmed. Charmed details the spells and occultic practices of three witches. The NKJV symbol is the show's primary symbol of witchcraft and is splattered throughout the series. Notice the NKJV symbol displayed on The Book of Shadows. The Book of Shadows is commonly used in withcraft and satanism

Christian use
The symbol has been used by Christians as a sign of the Trinity (Father, Son and Holy Spirit). The triquetra has been used extensively on Christian sculpture, vestments, book arts and stained glass. It has been used on the title page and binding of some editions of the New King James Version.
