According to Church Law, canons 1217 and 1218 in particular, a parish name must be:
- the name of the Trinity, or - a name for Christ, invoked in the liturgy, or a mystery of his life, or
- the name of the Holy Spirit, or - a name for Mary, invoked under a title for her used in the liturgy, or
- the name of a holy angel, or - the name of a canonized saint, as it appears in the Roman martyrology (or appendix), or - the name of a blessed provided the Apostolic See has given its permission.

The names of the former parishes, Holy Family/Notre Dame de Chicago, are retained until the Cardinal approves a new name.
