I was just wondering if there’s any truth to this?
No, the Church does not specify an amount. We are to be generous towards God, according to our ability. The bible is replete with verses regarding this, from the first fruits of Abel to the Widow’s Mite.
The Fifth Precept of the Church, from the
Catechism:
The fifth precept (“You shall help to provide for the needs of the Church”) means that the faithful are obliged to assist with the material needs of the Church, each according to his own ability.
Canon Law says this:
*Can. 222 §1. The Christian faithful are obliged to assist with the needs of the Church so that the Church has what is necessary for divine worship, for the works of the apostolate and of charity, and for the decent support of ministers.
§2. They are also obliged to promote social justice and, mindful of the precept of the Lord, to assist the poor from their own resources.*
It’s a serious obligation that we have to support the material needs of the Church-- the parish, the diocese, and the universal church. It is a serious obligation to support our priests, in active ministry and in retirement. It is a serious obligation to assist the poor through charitable works and through material support.
It is up to each of us to decide if we are giving generously or not. It is up to each of us to decide what is within our ability, and to revisit that periodically as our means change. As you get raises or change jobs, for instance, or if you receive a bonus, an inheritance, or other unexpected money. Also if you lose your job, or your pay decreases or expenses increase.
Additionally, our stewardship is not limited to money. We give the church time, talent and treasure. We work in the vineyards-- as the parable says-- doing to work of God in the corporal and spiritual works of mercy. We give our time to assisting at Mass through ministries, through teaching CCD or other classes, through working in social concerns ministries, giving to the food pantry or the resale shop or other works of the parish or diocese, Catholic Charities, etc. We give our time helping in these endeavors, or in community based works of charity. We give our talents-- are we a carpenter? We help repair the church if needed. Are we good at arranging flowers? We do bouquets for the altar. Are we good at bookkeeping? We offer to help with the parish in that way by serving on the finance council or doing the bookkeeping for the parish (large parishes hire full time bookkeepers, small ones like mine rely on volunteers).
But all of this is up to you via discernment in prayer.
