“todo el mundo” is a common phrased used in Spanish which literally means “all the world”. It’s a common phrase used when lots of people are involved. Just as in the passage Romans 5:12 doesn’t truly mean “all” in the literal sense, but is an expression. Jesus was Man and He didn’t sin and infants are incapable of sin. We know that no one is born with guilt of the sin of another, yet anyone can be affected by another’s sin.
Let me give you a real life example that just happened. Tonight, my daughter friend was riding his bicycle and a man driving a truck had roadrage, per the witnesses, and the man ran Justin down destroying the bicycle and injuring Justin. The man is the one who sinned with his anger/rage but the man wasn’t the only person affected by his sin. The man is the one going to jail tonight & will stand trial before a judge, but Justin was also affected. Justin is in no way guilty of the man’s sin, but Justin’s injuries were caused by the man’s sins.
Adam & Eve are guilty & will stand before the Judge for their own sins, but the rest of humanity was affected as through their sin which brought into the world Genesis says
- pain/sickness Gen 3:16
- The ground was cursed with weeds/necessititating hard work to grow food Gen. 3:17-18
- diseases/physical death Gen. 3:22-24.
Mary & Jesus, along with all the human race, were subject every one of these affects of the original sin, but none are guilty besides Adam and Eve of their first sin. Mary & Jesus were capable of personal sin, but uniquely chose not to. That we can expect from Jesus/God, but that is what makes Mary so extraordinarily amazingly & worthy of praise!
