How do Latin Catholics understand Filioque?

[Ghosty]

I quite agree. My only point is that an act of love can be thought of as mutual love between two Persons, yet using the same single divine will. My only use of the word “source” was in affirmation that there is but a single source.

I don’t expect to fully comprehend the Trinity even in heaven.

Forgive me if I misunderstood you, but your statement made it appear that the Father and Son are together the single source, which is false according to the Council of Florence. The Father alone is the single Source, but the Holy Spirit does indeed proceed from/through the Son.

As for the procession of mutual love, there’s a reason why such terminology has never been used to officially define the relations of the Trinity; it is problematic and perhaps a bit inaccurate. It’s too easy to make it a “Father and Son together are the Source” teaching, and while it’s been used by some Latin theologians, it’s never found favor in official doctrine nor in the Church at large.

Peace and God bless!
