Everything that happens at St Peter’s parish either leads to the SANCTIFICATION OF SUNDAY or flows from it. The following thoughts from Pope Emeritus Benedict XV1 can be the hinge around which your own life turns:                       

Sunday, is Dies Domini with regards to the work of creation, Dies Christi as the day of the new creation. Dies Ecclesiae as the day on which the Christian community gathers for the celebration, and Dies hominis as the day of joy, rest and fraternal charity.
Sunday thus appears as the primordial holy day, when all believers, can become heralds and guardians of the true meaning of time. It gives rise to the Christian meaning of life and a new way of experiencing time, relationships, work, life and death.
On the Lord’s Day, then, it is fitting that Church groups should organise around Sunday Mass, the activities of the Christian community: social gatherings, programmes for the faith formation of children, young people and adults, pilgrimages, charitable works and different moments of prayer.
Sunday itself is meant to be kept holy, lest it end up as a day “empty of God”

The Day of the Lord is also a day of rest from work. Christians not without reference to the meaning of the Sabbath in the Jewish tradition, have seen in the Lord’s Day a day of rest from their daily exertions. This is highly significant, for it relativizes work and directs it to the person: work is for man and not man for work. It is easy to see how this actually protects men and women, emancipating them from a possible form of enslavement.
“Work is of fundamental importance to the fulfilment of the human being and to the development of society. Thus, it must always be organized and carried out with full respect for human dignity and must always serve the common good. At the same time, it is indispensable that people not allow themselves to be enslaved by work or to idolize it, claiming to find in it the ultimate and definitive meaning of life”. It is on the day consecrated to God that men and women come to understand the meaning of their lives and also of their work.
