Today, it's hilariously illegal to put this kind of thing in an official employee communication. No government agency would even dream it.
Even in the 1960s, that kind of overtly religious appeal would have been very, VERY controversial. This kind of material _never_ appeared in military stuff, and I am very surprised to see it in NSA publications.

The Air Force barred an airman from reenlisting because he would not say "so help me God" in his oath, in 2014.[0]
To be fair, the military doesn't want to accept people who would disobey a direct order over something so petty. If they aren't mature enough to say "so help me God" and move on, they don't want them.
Insisting that the federal government obey by the Constitution is petty? For the government to enforce any religion on any level is strictly forbidden and the interpretation is even broader than that. It's the very first thing in the Bill of Rights.
It was the Red Scare. We added “under God” to the pledge of allegiance on the theory that undercover commies would explode if they tried to say it. I’m not surprised.
