Hey Gubmint!
If you don’t want a Christian prayer....don’t ask a Christian preacher.
“One has not only a legal but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws.” Martin Luther King’s words, which just correspond with the above assertion, perfectly tell us what to do in face of laws, either just or unjust.
What if he prayed in the name of Baal?
But ‘Allah’ would be accepted, no doubt.
