The Liberty Bell is an iconic symbol of American independence, located in Philadelphia, Pennsylvania. Formerly placed in the steeple of the Pennsylvania State House (now renamed Independence Hall), the bell was commissioned from the London firm of Lester and Pack (today the Whitechapel Bell Foundry) in 1752, and was cast with the lettering (part of Leviticus 25:10) "Proclaim LIBERTY throughout all the land unto all the inhabitants thereof." It originally cracked when first rung after arrival in Philadelphia, and was twice recast by local workmen John Pass and John Stow, whose last names appear on the bell. In its early years, the Liberty Bell was used to summon lawmakers to legislative sessions and to alert citizens to public meetings and proclamations.
Above is form Wikipedia. The Liberty Bell was cast in 1752 in England. The inscription from Leviticus therefore had no connection to the faiths of the Founding Fathers. I'm sure many of the "facts" from Thom's guest would have similar histories.
