Protestants, including myself, believe that the Bible is true. Therefore, any belief that contradicts it can not be true. Because the Bible specifically prohibits contacting the dead, we do not pray to saints. Furthermore, when the disciples asked Jesus how to pray, the prayer that Jesus gave them was addressed to “Our Father.” Jesus never felt the need to expand this teaching. This is why Protestant do not pray to saints.
