Social Distancing Guidelines for the Celebration of Mass 

Prevent and Protect STL

The Archdiocese of St. Louis has developed a new system for safe environment compliance called Prevent and Protect STL.  Everyone ministering to minors or vulnerable adults or making home visits for SVDP (clergy, employees and volunteers) in the Archdiocese are required and asked to register in the new system before December 31, 2020.  This includes those new to service and those who are currently in service.  For those who have already attended a Protecting God's Children workshop, your previous training date will transfer to this system.  Those new to the service must attend a live Protecting God's Children workshop.  Everyone, new to service or currently in service will register for an updated background screening, view two new online training modules on abuse reporting and the Code of Ethical Conduct, and agree to the updated Code of Ethical Conduct.
