Do I have to come to mass every Sunday, I work weekends, nights and Sunday.

There are 5 precepts or necessary minimums in the spirit of prayer and moral effort, in
the growth in love of God, and neighbor that each Catholic must do (CCC2042-3):
1) to attend Mass on Sundays and other holy days of obligation and to refrain from work and activities which could impede the sanctification of those days.
2) to confess one’s sins, receiving the Sacrament of Penance at least once each year.
3) to receive the Sacrament of the Eucharist at least once a year during the Easter season.
4) to abstain from eating meat and to observe the days of fasting established by the Church
5) to help to provide for the needs of the Church, obliged to assist with the material needs of the Church, according to ability.
Sunday mass sanctifies the day commemorating the Resurrection of the Lord as well as the principal liturgical feasts honoring the mysteries of the Lord, the Blessed Virgin Mary, and the saints by participating in the Eucharistic celebration, in which the Christian community is gathered, and by resting from those works and activities which could impeded such a sanctification of these days” (CCC2041).
It is understandable that we need to work to sustain ourselves and our families. But, once a week, especially to commemorate the Resurrection on Sunday, we need to give thanks for all we have been given to include our means of providing for our families. It puts in order where our trust is, in God for all things above all things. It is so important that it is one of the first three commandments. To make it even more accessible because of the importance of going to mass, Fr Robert has set up for our parish five different masses, Saturday night 5pm, Sunday at 8:30am, 10:00am, 11:30am and 6pm.
Without the precept reminder of the mass and its thanksgiving it becomes easy to think our trust is in things over God who provides all things. Christ's presence in the Eucharist sustains the Church, as we heard in Tuesday's mass readings in Ephesians 2:19-22, Christ and His life is the capstone that holds our Church together. Through the Eucharist we grow similar to how everything needs the sun. Even if we do not or cannot receive Him at mass, He is there reaching out like rays of Divine Mercy holding us together and healing us through HIs presence. Mass and especially the Eucharist reminds us we are made in communion for each other made in the image of our Triune God radiating HIs presence we receive. Mass obligation on Sunday sets our priority of trust and thanksgiving for the week coming ahead so that no matter what befalls us we lean on God knowing He is our all in all. Jesus we trust in You.
