“faith without works is dead.” (James 2:20). I dont believe that Sola fide is biblical. As men of faith, we have to strive to enter by the narrow gate for, as Jesus said, not all who say Lord, Lord shall enter (cf. Luke 13:23-28).
That's whay the Church taught and still teaches 2,000 years later. We can't simply "accept" Jesus and get a limo ride to heaven.
