Gerhard Ebersoehn: Paul does not deal on all or just any 'holy days' in Ro14, but specifically on the Passover, it being the only festival of 'holy days' that fits every specific indicated in Romans 14. Eric B: The Passover is not even mentioned in this passage! I don't see how you can just by fiat add something that is not there! GE: The Passover needs no mention by name; it is proven the subject through elimination. Every specific fits the Passover and the Passover only. There is no property supposed or mentioned that alludes to the Seventh Day Sabbath. That this passage does not treat on the Christian duty of Sabbath-observance, proves nothing in the line of no Sabbath-validity for the Christian Church. There are many other Pauline and Lukan statements to the effect the Sabbath remained indispensable fibre of Christian coherancy and mission. The Gospels came much later than any of these documents that without variance presuppose Christian Sabbath's-belief and practice, and they, take the Seventh Day Sabbath for granted as an a priori Reality, Necessity and Prerogative of no one less than the Son of Man Himself, let alone of His followers both disciples and Apostles.
