[Full Court]

The Bible says that husband and wife do not withhold sex from one another except for prayer and fasting.

1 Corinthians 7:4  The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.

5  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.

[Cronos]

The Bible says that husband and wife do not withhold sex from one another except for prayer and fasting.

1 Corinthians 7:4  The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.

5  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.

Neither of those statements say that a wife sins by not sleeping with her husband, except by your inference, your personal, individual, flawed, interpretation.  In fact neither statement even talks about sex...

Not to do some trademark Protestant tangent jumping myself, but I've also seen Protestants use the argument that Catholic clerical celibacy is unbiblical because Jewish rabbis (who one could argue the priesthood is modeled after) had to be married. Of course, Jesus Himself was a rabbi and celibate.
