You just said that they could use a secular oath.
Did you miss the part that asking for one puts
the court on notice that one isn't a Christian?
There just might could possibly cause some
prejudice against the one testifying.
Is it oaths in general that you oppose?
I don't see the need, but if the oath is just
an affirmation to be truthful, their GOD has
nothing to do with it. He obviously hasn't
made Christians all that honest.
This is a legal standard that allows for perjury prosecutions.
It's not necessary. For example, lying to a
cop is a crime without ever swearing an oath
or even being put on notice that it's a crime.
But that's beside the point about having the
court made aware that one isn't Christian,
& the risk of prejudice against one.
What good is a legal statement if there is no consequence for lying?
Not the point at all.
