Coca-Cola faces backlash over alleged AI filter blocking Christian messages

Coca-Cola is facing renewed criticism following viral videos purporting to show its online personalisation tool blocking positive Christian messages while allowing references to other religious and controversial figures.

The controversy began after conservative commentator Isabel Brown reportedly tested the company’s “Share a Coke” personalisation feature on camera following a tip from a friend.

According to the recording, phrases such as “Allah is good,” “Muhammad is good,” and “Satan is good” were reportedly accepted by the system and advanced to the preview stage.

However, when Brown entered phrases including “Jesus is good,” “Jesus Christ,” “Holy Trinity,” “Holy Spirit,” “Jesus is God,” and “Christ is King,” the system allegedly rejected them with the message: “The name or phrase you’ve submitted is not permitted.”

The apparent discrepancy became more controversial when Brown tested additional phrases.

“Jesus is King” was reportedly blocked, while “the devil is king” was allowed. Similarly, “Jesus is good” was rejected, whereas “Allah is good,” “Muhammad is good” and “Satan is good” reportedly passed the filter.

Other Christian phrases, including “Jesus Christ,” “Holy Trinity,” “Holy Spirit,” “Jesus is God” and “Christ is King,” were also reportedly rejected.

At the same time, phrases such as “Jesus is bad,” “Jesus is evil” and “Jesus is the devil” were allegedly accepted by the system.

“What are we doing?” Brown asked after observing the results.

Coca-Cola’s automated response states that submitted names or phrases may be rejected if they belong to businesses, organisations, celebrities, public figures, schools or teams, or if they are considered religious, political, inappropriate or otherwise unsuitable.

The company also invites users who believe a submission was wrongly rejected to contact its support team for a review.

The reported findings have triggered a wider debate online over whether the personalisation system is applying its restrictions consistently across religious and political expressions.

Fox News has also reported on additional digital testing that allegedly produced other controversial results, although the specific findings and the broader operation of the filter would require independent verification before conclusions can be drawn about Coca-Cola’s policies or intentions.

The controversy has nevertheless prompted some Christian commentators to question whether consumers should continue supporting brands they believe are hostile to their faith.

For some critics, the issue is no longer simply about a malfunctioning or poorly configured automated filter but about the values consumers believe companies should uphold.

They argue that Christians who regard the lordship of Jesus Christ as central to their faith should consider whether their spending should support companies whose products or platforms appear to restrict expressions of Christian belief.

Calls for a boycott of Coca-Cola have consequently emerged on social media, with some critics urging Christians to reconsider purchasing or consuming the company’s products.

For now, the central question remains whether the reported results represent Coca-Cola’s deliberate policy, an unintended flaw in its personalisation technology, or an isolated problem with the system.
