Living the Gospel, pg. 218; “One of the main and logical reasons for not engaging in commercialized amusements, is that it causes numerous other persons to be obliged to work. Thus they have to forego both the rest and chance to worship on the Sabbath day….The other reason for not engaging in unnecessary recreational activities, just as important as the first, is that we ourselves have neither time nor inclination to “go to the house of prayer” and offer up our sacraments upon that holy day which the Lord has appointed unto us to pay our devotions to the Most High.” – Gerrit DeJong, Jr.
Exodus 20:8-11; “Remember the sabbath day, to keep it holy. 9 Six days shalt thou labour, and do all thy work: 10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.”
