On the other hand, some passages of the New Testament indicate that certain aspects of the law were no longer applicable in the time of the New Testament, at least not in the same way that they were to be kept in the time of the Old Testament. See for example the following story of how Peter was told that he could eat things that were considered impure during the Old Testament times:

About noon the following day as they were on their journey and approaching the city, Peter went up on the roof to pray. He became hungry and wanted something to eat, and while the meal was being prepared, he fell into a trance. He saw heaven opened and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles of the earth and birds of the air. Then a voice told him, "Get up, Peter. Kill and eat." "Surely not, Lord!" Peter replied. "I have never eaten anything impure or unclean." The voice spoke to him a second time, "Do not call anything impure that God has made clean." (Acts 10:9-15)

QUESTION:

Which position regarding the use of the O.T. law is refuted by Acts 10:9-15?
