QUESTION: Is there any scripture that says Priests and Nuns should not marry?

ANSWER: It is obvious to all that the Catholic Church forbids their Priests and Nuns to marry. That forbidding to marry is wrong can clearly be seen in I Timothy 4:1-3. Those who do so are those who have departed from the faith (vs.1)! Nonetheless, one may make a personal decision not to marry, provided that he or she does not succumb to the temptations that often befall a single person (I Corinthians 7:8-9). The apostle Paul is an example of one who chose not to marry! But this same apostle tells us in I Corinthians 7:1, “to avoid fornication, let every man have is own wife, and let every women have her own husband.” So we see that a decision to marry, or not to marry, is a choice that each person has to make and, further, that the decision should be made only with careful consideration to biblical principles. The sin of religious people and organizations relative to marriage (and many other issues) is that they make laws where God has not legislated. In other words, they proclaim a gospel that is different from the New Testament. These are to be accursed (Galatians 1:6-9)!
