are you a judeao christian? if so why would you invite a group into your home to plant a seed of doubt in your heart. If Ive been educated properly on them they believe in salvation through work I believe in salvation through the Crucifixion of Christ, faith in that results in good work not good work results in faith. they claim to have new books in the bible, I'm not sure of their origin or even what they teach but be very careful not to allow your faith in Christ to be tainted by swift tongue salesmen.
