Welcome to

St. Mary Immaculate Parish

A Roman Catholic Parish in the Diocese of Joliet

15629 S. Rt. 59, Plainfield, IL 60544     815.436.2651



Jesus said to his disciples: “The kingdom of heaven is like a treasure buried in a field,
which a person finds and hides again, and out of joy goes and sells all that he has and buys that field. Again, the kingdom of heaven is like a merchant searching for fine pearls.
 When he finds a pearl of great price, he goes and sells all that he has and buys it.
Again, the kingdom of heaven is like a net thrown into the sea, which collects fish
of every kind. When it is full they haul it ashore and sit down to put what is good
into buckets. What is bad they throw away. Thus it will be at the end of the age.
The angels will go out and separate the wicked from the righteous and throw
them into the fiery furnace, where there will be wailing and grinding of teeth.

“Do you understand all these things?” They answered, “Yes.” And he replied,
 “Then every scribe who has been instructed in the kingdom of heaven is like
the head of a household who brings from his storeroom both the new and the old.”

- Matthew 13:44-52

Volunteers Needed

Are you looking for an opportunity to get more involved with our parish? So much of the wonderful work done at SMI wouldn’t be possible without volunteers. If
you like having donuts after
mass, how about being the
family who serves them? If
you’ve experienced the kindness
of someone during a time of
need, why not pay it forward
by being part of the Funeral Luncheon Ministry? Do you like helping to plan events? You can contribute to the success of
parish workshops and
celebrations by joining the Fellowship Team.

Please contact Laura Van Ham
at or 815-436-2651, x887 for more information and to join one of
the following teams:

Brothers In Christ


The ministry of Brothers in Christ is a group of men who seek to help one another become better men through developing our relationship with Jesus. We acknowledge that we are all on a personal faith journey. Some of us are novices, some more experienced, and others, perhaps, just waiting to grow spiritually. We have many backgrounds and many gifts, but we share the same spirit. That spirit is the spirit of love and we do all we can to help one another, by being Christ in all his compassion for one another. We learn from the Word of God, meditation, readings, and our unique life experiences as men. You will find that our meetings are full of spirit, laughter, and inspiration. It is easy to feel the Holy Spirit moving and working within us individually...READ MORE
