Really?!
You mean God wasn't capable of having Mary free of original sin?
Where did you get this Divine information?
You're advancing Dunn's argument which is a weak argument to justify the Immaculate Conception.
God is capable of doing whatever He wants. However, He will not contradict Himself.
Where did you get this Divine information?
IF one reads the Bible one will realize that everyone born of man and woman since the Fall is a sinner.
There are no carve outs for Mary in this regard.
You mean God wasn't capable of having Mary free of original sin?
The better question would be is God capable of preserving Christ in the womb from the effects of sin with the need of Mary being sinless??
Read the Bible.
King James Romans 3:23
“For all have sinned, and come short of the glory of God”
God could have created Mary without sin, but he didn’t according to His word the Bible. All includes Mary and she sinned.
God cannot lie and therefore he would not contradict His word.
Hebrews 6:17-18
“His purpose is unchangeable, confirmed it with an oath, so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to hold firmly to the hope set before us.”
If the Bible is not true, that makes God a liar and you might as well be an unbeliever.
