Think not that I am come to destroy the law,…

Does Church of God as a whole believe that we are still under the law? I spoke with with a CoG Bishop who indicated we were still under Mosaic Law and gave this scripture as support.

“Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.”
‭‭Matthew‬ ‭5:17-18‬ ‭KJV‬‬

Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
