ILYM is a spiritual community of Quakers, also known as the Religious Society of Friends. Though the individuals in this community attend some 21 affiliated local Meetings across four states, each summer the Meeting gathers in a retreat near McNabb, Illinois to worship together and to conduct the business of the community. This business includes issues related to lay ministry, religious education, the practice of faith, volunteer service, public witness, publications, Meetinghouse site improvement, and finances. The ILYM Meetinghouse is also the worship site for Clear Creek Friends, as well as for workshops, retreats and committee meetings.
ILYM includes Blue River Quarterly Meeting and has an overlay with Metropolitan Chicago General Meeting of Friends. Histories are available for Blue River Quarterly Meeting and Meetings in the area of Chicago General Meeting.
