CREDO ? I BELIEVE When you read the Bible, you will find that there is quite a big difference between what is written there and what is taught in most churches today. Many have observed this. Reformers like Zwingli, Luther and Calvin intended to return to the original faith, to what Yeshua and his disciples believed and taught. Others took over the work of returning to our Hebrew roots, but the goal has not yet been attained. For those that have not seriously read their Bibles this may come as a surprise.
