They should take care. If the Bible thus consumed is truly digested, it will get into their bloodstream. This would make a good horror movie for progressives.
The Good Activist eats the family bible at a highly publicized "last supper." That night spiritual beings (demons sent by Donald Trump to torment him -- or so he thinks) appear -- which he puts down to a nightmare caused by acid reflux until they linker into his waking hours. These demons struggle with his angelic system of ordained Marxist Beliefs. He thinks he is becoming delusional as life lessons from the Bible sneak into his thoughts. He begins to feel unfamiliar sensations like happiness, tolerance (as opposed to "tolerance"), and respect for others. He is no longer hostile to the diversity of thought but instead finds encountering other points of view stimulating.
As the fog of depression lifts from his mind, he realizes the spiritual beings are actually his ancestors whose traditional beliefs appeal to the better angles of his nature. For instance, he no longer believes Clarence Thomas is a White Supremacist. He finds that he can now speak obvious truths and even smile as he is canceled and the red carpet leading to a full professorship is yanked from beneath his feet. His former associates are aghast but that's OK because he can now function in the real world and no longer needs the "reality-based community" to feel a weak, uncertain, and fleeting sense of purpose.
