The lawmakers said they oppose a decision to remove the phrase "Doing God's Work" from the patch for the Air Force Rapid Capabilities Office, The Hill reported Wednesday.
In its place, the Air Force substituted the phrase "Doing Miracles" last month.
The patch logo was changed after a military atheist group protested the reference to God that was written in Latin.
"The action taken by the RCO suggests that all references to God, regardless of their context, must be removed from the military," said the group's leader, Rep. Randy Forbes of Virginia. "We ask that you reverse this perplexing decision."
Forbes said the group is confident the Air Force's lawyers "would not suggest that censorship is required for compliance with the First Amendment."
