Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. Life is a wonderful mixture of change, and stability. There are some things that never change. Babies are born into this world today exactly like they were 6000 years ago. People still breathe oxygen and still eat dinner.
Spring still comes after winter.
And fall still comes after summer. Yet others change all of the time. We want the rain to change to sun. Jesus told us to beware of clinging to traditions of men. Some things have changed in churches over the centuries.
