We always have more requests for help from our pantry guests than we have donors. We’ve a great idea to make the sponsorship work for all. Would you like to help provide a meal for one of the families who come to our pantry? Our average family size is four, and we have many families with 7 or more children.

Many people struggle every week to find the resources to prepare nutritious balanced meals for the family table. Often there’s nothing extra after holiday season ends to prepare the kinds of daily meals so many of us take for granted. A Scrip card from Target, Walmart, Jewel or Meijer could help make their days brighter by allowing them to choose the food items for their families..

If you want to help, please consider purchasing a Scrip card through the weekly program here at St. Irenaeus and drop your card(s) into the box that will be provided before and after every Mass. Our families will gladly use the cards to buy the ingredients for favorite traditional dishes, desserts or perhaps diapers for the baby or bathroom tissue or other essentials. The need is huge.

Thanks for all your prayers and donations of food and money for the pantry program. We couldn’t do this without each of your contributions!!
