There is some discussion about why God created man here. The answers go something like "God wanted to love us, share his perfection/happiness/life with us. Therefore, he created us."
Yet, God also created angels. Beside some fallen angels, most of them are in Heaven, already enjoying the beatific vision of God face to face. There was no salvation process involved. No sin. No pain. These are spirits (i.e. bodyless souls) created to be happy.
So, the question is, why did God create souls in the form of men, rather than creating these souls in the form of angels? The answers to the linked question do not address this issue.
The context of this question relates to the problem of evil. God sharing his life with us whilst respecting our freedom is a "classic" answer to the problem. However, this still begs the question of why God created man as man rather than as angel.
PS: there is a related question here but it is not denomination specific, and the answer does not really answer the question, imo.
