Is the finished work of Christ “just semantics“?

What is modalism? How do I convince someone to abandon it in favor of the Trinity? I’m a newlywed, and I want my husband to understand the message of God’s grace to the fullest. What can I do? My youth pastor seems to be teaching some things that don’t quite align with the gospel. How can I handle that?
