“Then God blessed the seventh day and made it holy,because on it he rested from all the work of creating that he had done.”
In this verse there are very important hebrew words. The first one is “to bless” and it was used when God create the mankind. (Cf. Gen 1:22.28). To bless means that something or someone is specially protected by God. It si also said that God “consacrated” the seventh day, namely he filled it with His holiness. So the seventh day has been “distinguished” from the other days of the week (6+1), because the seventh day has to be dedicated to God. Does it mean that one has to do nothing in that day? It means that in that day men and women have to do something else.
In Hebrew the number seven symbolize the “totality, entirety”. So the week doesn’t esist without the seventh day. The first seven days of the week are deprived of purpose and meaning without the seventh day. In fact, the hebrew word week (shevuah) is very close to the verb “to rest” (shavat) the verb from which the word “saturday” comes (shabbat). It is not only a matter of similar sounds, because there is a deep relationship between the six days of week and the seventh day that is the goal of the week.
As God ceased to work in the seventh day God, men and women have to cease their work too. They have to devote themselves to other activities: they have to spend time with family, or they can spend a day in the nature. But they don’t have to forget to participate to sacred rite. This means not only to attend the Mass, because the sacred rite is made of language, space and time, where men and women recall the true purpose of their life. The sacred rite, in fact, is the main element of every religion, because every religion is a space where earth communicates with heaven. Sacred rite is a dimension where the time communicates with the time and the space of God. Look at this interesting video:
