In this discussion of food, Paul touches on the second reason for not using or referring to Old Testament Scriptures, i.e. the fulfillment of the Old Testament Law. TWO Those who try to justify the forbiddance of homosexuality through the use of the Leviticus and other similar passages, bind themselves to the requirement to adhere to all Old Testament Law. This is invalid. The foundational truth of Christianity is Christ fulfilled the Law, the Law now void, believers now under a different code. But if ye be led of the Spirit, ye are not under the law.
Believers are under only one law, the Law of Christ, the Law of Love.
If you try to live under the Law, you shall fail, but if you live under the Law of Love, you shall fulfill all Law. One day just a person, then through the birth or adoption of a child, you become a parent. You must be responsible in the child's care and welfare, providing food, shelter, clothing, teaching and training how to live properly in the Faith and our Society. Because your child was not your focus, rather your focus was all those duties and responsibilities. If we determine to live up to these duties, whether real or imagined, we shall miserably fail.
