What we need to learn from this is to never, ever, read any scripture without putting it into the context of all other scripture.
First, we must look at the book of Acts, telling of the transition for both Jews and gentiles to their world that Christ made, To do that we need to know a lot about the world as it was when Christ changed it. Jews were under the sacrificial system needing to learn to use the blood of Christ when their parents had always trained them in a different way. Gentiles had idols and superstitions, and were just beginning to see the true God, but scornful of living a life with a strange diet, and strange ways that made no sense. Jews were afraid of letting heathen gentiles into their world.
Then we need to study what and why gentiles and Jews needed to do to make the one true God their God, and sift out the legalistic demands from the true demands of spirit and truth. How was this done? What of the instructions was truth and what was only legalistic?
Without any of this background of understanding what led to this verse, you cannot decide just what the Lord wants us to know by this one verse.
