Ye observe days and months, and times and years.

I am afraid of you, lest I have bestowed upon you labor in vain.Gal.iv.10, 11.

And still more clearly in Colossians ii.

16, 17.

Let no mint therefore judge you in meat or in drink, or in respect of an holy day, or of the new moon, or of Sabbath days: which are a shadow of things to come." "But although the Sabbath is _now revoked_, and the consciences of men are free from it, it is nevertheless good and necessary that _some_ particular day of the week be observed, in order that the word of God may be dispensed on it, may be heard and learned; for not every one can attend to it every day.
Moreover, nature demands that both man and beast rest one day in the week, and abstain from labor.
