Because the Jews, particularly the Pharisees, were so very superstitious in keeping the Sabbath, they would not recognize Jesus as the Messiah, while He healed on the Sabbath, which was really a good work. But, if the Jews were so conscientious, through superstition and hypocrisy, and considered the performing of an external good work on this day as a sin, some Christians, on the contrary, blinded by avarice and worldly pleasure, place themselves heedlessly, nay, insolently above the commandment to observe the Sabbath, and do not consider those things as wrong which are sometimes very grievous sins.
Consider, my dear Christian, you serve your body the whole week, you use all your powers for temporal business, to support yourself and your family, and God blesses you, if you work with a good intention. Now God chose one day in the week, Sunday, and in the year several other holidays, which you should devote to His service and the salvation of your soul; is it not, therefore, the greatest ingratitude to steal these days from God and your soul, and employ them to gain a transient good, or to indulge in vain, sinful pleasures? At certain times man gives rest to irrational animals, and you give the powers of your body and soul none of the rest they would and should find in quiet devotion, in prayer and meditation, in attending divine service, in receiving the holy Sacraments, &c. If you inquire whence come these shameful violations of Sundays and holidays, you will find that there is no other reason than love of gain and avarice, sinful love of pleasure, and often complete want of faith and confidence in God's providence. We wish to become rich by all means, and we do not reflect that. this will not happen without the blessing of God, and that wealth is a net, in which thousands entangle themselves to their eternal, perdition. We wish to live merrily and enjoy ourselves, but we do not consider that our life is only a time of penance, to attain that eternally blissful rest, of which Sunday is an emblem. We spend Sundays and holydays in idleness, vain conversations, buying and selling, servile work, or in still worse things, without experiencing the slightest scruple. But God will cover the violators of His sacred days with confusion and shame, (Malach. II. 3.) and permit many temporal evils to come upon them, as proved by daily experience. The blessing of God can never rest upon those who never care for it, but rather make themselves unworthy to receive it, by violating days consecrated to God. Let this be a warning to you.
