“Something has got to hold it together. I'm saying my prayers to Elmer, the Greek god of glue.”

Bildung, 1890. Alle Verk, xii. 14.
Context: The Hebrew language... is the only glue which holds together our scattered bones. It also holds together the rings in the chain of time.... It binds us to those who built pyramids, to those who shed their blood on the ramparts of Jerusalem, and to those who, at the burning stakes, cried Shema Yisrael!

Ford is known to have used the words "truth is the glue that holds government together" several times prior to this.
1970s, First Presidential address (1974)
Context: I believe that truth is the glue that holds government together, not only our Government but civilization itself. That bond, though strained, is unbroken at home and abroad. In all my public and private acts as your President, I expect to follow my instincts of openness and candor with full confidence that honesty is always the best policy in the end.

The Serpent, Adam, and Eve, in Pt. I, Act I
1920s, Back to Methuselah (1921)
Context: THE SERPENT: The voice in the garden is your own voice.
ADAM: It is; and it is not. It is something greater than me: I am only a part of it.
EVE: The Voice does not tell me not to kill you. Yet I do not want you to die before me. No voice is needed to make me feel that.
ADAM [throwing his arm round her shoulder with an expression of anguish]: Oh no: that is plain without any voice. There is something that holds us together, something that has no word —
THE SERPENT: Love. Love. Love.
ADAM: That is too short a word for so long a thing.

Context: Core ideology provides the glue that holds an organization together as it grows, decentralizes, diversifies, expands globally, and develops workplace diversity. Think of it as analogous to the principles of Judaism that held the Jewish people together for centuries without a homeland, even as they spread throughout the Diaspora. Or think of the truths held to be self-evident in the Declaration of Independence, or the enduring ideals and principles of the scientific community that bond scientists from every nationality together in the common purpose of advancing human knowledge. Any effective vision must embody the core ideology of the organization, which in turn consists of two distinct parts: core values, a system of guiding principles and tenets; and core purpose, the organization’s most fundamental reason for existence.
