Every online religious service of The Satanic Temple opens with the minister reciting the Invocation of The Satanic Temple. The invocation was written by Lucien Greaves, and is frequently incorporated into rituals and TST events.

This is the text of the Invocation of The Satanic Temple:

Let us stand now,
unbowed and unfettered
by arcane doctrines
borne of fearful minds in darkened times.
Let us embrace the Luciferian impulse
to eat of the Tree of Knowledge
and dissipate our blissful
and comforting delusions of old.
Let us demand
that individuals be judged for their concrete actions,
not their fealty to arbitrary social norms
and illusory categorizations.
Let us reason our solutions
with agnosticism in all things,
Holding fast only to that which is demonstrably true,
Let us stand firm
against any and all arbitrary authority
that threatens the personal sovereignty of One or All.

That which will not bend must break,
and that which can be destroyed by truth
should never be spared its demise.
It is Done. Hail Satan
