The poster didn’t claim that was his opinion but made a claim for the church.
Can you refute the claim?
The poster was speaking as an individual, stating an opinion on Catholic belief. Tot he best of my knowledge this is not Pope Francis or a member of the College of Cardinals. Therefore it is an opinion.
Can you refute the claim?
The CCC is available online for all to see. You have made the claim to be Catholic, you should know what Catholic teaching is. If what you said was accurate.
