1 Corinthians 7:5 (Whole Chapter)
Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
If a husband and wife agree to abstain from relations for a time of dedication, that's one thing. But, to say that they HAVE to abstain on EVERY Sabbath (which is Saturday, by the way) is absolutely ridiculous. Even if it WAS a commandment under the law, Jesus addresses it as thus:
Mark 2:24
And the Pharisees said unto him, Behold, why do they on the sabbath day that which is not lawful? Mark 2:27
And he said unto them, The sabbath was made for man, and not man for the sabbath:
...and woman
