Are Christians no longer welcome in our military?

According to an article in Fox News, soon, the Navy will have a new oath for members to take. It will be an oath to support “intersectionality”.  wikia.org defines it:  

“Intersectionality is a concept often used in critical theories to describe the ways in which oppressive institutions (racism, sexism, homophobia, transphobia, ableism, xenophobia, classism, etc.) are interconnected and cannot be examined separately from one another.”  

The oath looks like this: “I pledge to advocate for and acknowledge all lived experiences and intersectional identities of every sailor in the Navy. I pledge to engage in ongoing self-reflection, education and knowledge sharing to better myself and my communities. I pledge to be an example in establishing healthy, inclusive and team-oriented environments. I pledge to constructively share all experiences and information gained from activities above to inform the development of Navy-wide reforms.” 

By the 3rd century A.D., Christians were no longer serving in the Roman army. Many had already opted out, and some had been murdered, because of the necessity of offering a sacrifice to the emperor. Christian theologians began drawing up reasons why Christians couldn’t be soldiers any longer.

We might be coming full circle. And the question is: when Christians are no longer permitted by their conscience to serve in our military, where will our military find salt and light?
