I imagine that the women of the parish also assisted in many other ways like they do now, such as laundering and caring for the altar linens, arranging the altar flowers, cleaning the church, cooking for social gatherings, assisting with missionary work through the Legion of Mary, that kind of thing. That’s what we do at my current parish.
The men tend to do the “manly” things around the church, like plant flowers and assist in the landscaping of the parish grounds, repairing things around the building, act as ushers during Sunday services, etc.
There’s tons more to do at a church than simply to perform the mass as a Priest does, or serve as an altar boy or server. I pray daily for the humility to be able to serve in ways that conform to God’s will. I also pray daily that I will become humble, but not know that I am humble, and holy, but not know that I am holy, lest I be tempted by the sins of pride and vanity. I have a very simple task that I help with every week at church, and the simplicity and lowliness of the task brings me great happiness, because I do it solely with the intention of glorifying God. Often they ask me to help with a more “fun” or glamorous task, and I say, “No, I’m quite happy doing this. Thank you, though!”
