Are the Father, Son, and Spirit three separate spirits and souls or one spirit and soul?
In contrast, angels are pure spirits but created ones.
The Father, Son, and Spirit are each distinct, uncreated spirits, and it’s important to emphasize distinct rather than separate. They each wholly possess the same divine nature, united in the Holy Trinity. So we have one God, because they wholly possess the same divine nature, and yet they are three distinct, divine persons. Of course, only the Son became man, so he also has a human soul and body.
For more on the Trinity, see CCC 232ff.
