The word of the law is θέλημα.
~ Liber AL I:39 ~

​I believe in one secret and ineffable LORD; and in one Star in the Company of Stars of whose fire we are created, and to which we shall return; and in one Father of Life, Mystery of Mystery, in His name CHAOS, the sole viceregent of the Sun upon the Earth; and in one Air the nourisher of all that breathes.

And I believe in one Earth, the Mother of us all, and in one Womb wherein all men are begotten, and wherein they shall rest, Mystery of Mystery, in Her name BABALON.

And I believe in the Serpent and the Lion, Mystery of Mystery, in His name BAPHOMET.

And I believe in one Gnostic and Catholic Church of Light, Life, Love and Liberty, the Word of whose Law is ΘΕΛΗΜΑ (Thelema).

And I believe in the communion of Saints.

And, forasmuch as meat and drink are transmuted in us daily into spiritual substance, I believe in the Miracle of the Mass.

And I confess one Baptism of Wisdom whereby we accomplish the Miracle of Incarnation.

And I confess my life one, individual, and eternal that was, and is, and is to come.
