How did the Holy Spirit perform this miraculous “Immaculate Conception”?
Possibility #1: the Holy Spirit provided the male sperm necessary
Possibility #2: the Holy Spirit “created” the fetus in Mary’s womb
On what basis do you think it is sound/appropriate for you to impose human reproduction limitations on God ?!!!
How did your God create the universe? Did he not WILL it into existence?
Why then should that god need sperm or a fetus?
You're trying to shackle your God or the Spirit with human limitations instead of realising that God can do anything. He has "Free" will to manifest anything he likes.
