Shouldn't every judge on the Supreme court be a declared Atheist?

Skipping over this Kavannaugh mess for a moment.
The Supreme court is there to oversee the rule of law for all citizens throughout the land. The statue of Justice holds scales to evenly weigh evidence and wears a blindfold to block out anything else from her deliberations. Since race and religion are possible influences, and since race is outlawed as a legal reason to be influenced, while religion is at the core of believers values, wouldn't it make sense that only judges who had no loyalty higher than the law of the land should sit on its highest court?
