Kentuckians will again be able to sign up for a Christians-only medical program under a batch of new laws that take effect Tuesday.Lawmakers passed the law allowing Medi-Share, a Florida-based cost-sharing ministry, to resume operations in Kentucky, reacting to a judge's ruling that barred the program from the state.That law, along with dozens of others taking effect Tuesday, allows churchgoers who sign pledges not to smoke, drink, use drugs or engage in sex outside of marriage to sign with Medi-Share. State Sen. Tom Buford, chairman of the Senate Banking and Insurance Committee, said the new law is crucial to many Kentuckians because Medi-Share costs, which average about $300 a month, are far less than traditional insurance plans.
