Perhaps the person who wrote this blog article simply doesn’t understand what Akin wrote. I looked at Akin’s original article and it seems obvious to me he is saying there will be many grave sins objectively speaking but not everyone will be held to be blameworthy because of their ignorance.
Perhaps you should reflect carefully on what I have written. Sacred Scripture refers repeatedly to the Day of Judgment as a Day of Wrath.
Reflect very carefully on that fact.
And consider Our Lord’s warning: ‘Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.” (Matthew 7: 21).
I’m sorry you find this Scripture to be “inconvenient.” Reflect too on Our Lord’s warning that the way to perdition is broad and MANY there are who travel on it. But narrow is the way to salvation and FEW there are who find it.
Meditate carefully as well on the warning found in James 2: 14: “What good is it my brothers, if someone says he has faith but does not have works? Can that faith save him?”
And then we have the warning found in Lumen Gentium, No. 14: “All the Church’s children should remember that their exalted status is to be attributed not to their own merits but to the special grace of Christ. If they fail, moreover, to respond to that grace in thought, word and deed, NOT ONLY SHALL THEY NOT BE SAVED BUT THEY WILL BE THE MORE SEVERELY JUDGED.”
