If you need something not covered by the doctrine of Fair Use, there are ways to license what you need. You can either license per song or subscribe to an umbrella license that covers the catalogs of multiple publishers.
Christian Copyright Licensing International (CCLI)
Useful if you need to reprint music for worship services or show them on a screen. They also have a separate performance license for streaming music during worship services.
OneLicensing
Useful for a smaller number of publishers than CCLI. They offer print and streaming licenses for a single event as well as annually.
Christian Copyright Solutions
Provides licensing for performance of many different publishers. They partner with BMI, an international music licensing company.
In most cases, duplicating copyrighted printed music without obtaining an appropriate license is not allowed. However, some special circumstances arise that permit copying, most usually when the work is not intended for performance but used in a classroom setting.
These follow the same guidelines as course packets that use other printed materials, with the added caveat that they may not be used for the public performance of the music. Every musical excerpt in a course packet, if derived from copyrighted material, requires permission, either from the copyright owner or through checking with the Seminary’s copyright umbrella licenses, such as Christian Copyright Licensing International to see if the excerpt is covered, and if not, paying a royalty fee to the owner. Each item in the packet also must include a notice of copyright -- e.g., "Copyright 2020 by Michael Joncas." Individuals who purchase course packets should not be charged in excess of cost. Expect several weeks' delay in cases where copyright owners are elusive.
Music, readings, and lectures, whether recorded, streamed on the internet, and/or performed live, are protected by copyright law. The exceptions are when the music has been licensed in the Creative Commons or is in the public domain, as earlier described.
Performances. Most performed music in the Seminary falls under two distinct categories, and each is treated in slightly different ways. The most obvious is during a religious observance, such as the weekly chapel service. However, classes may use music during a class setting, whether recorded or performed.
