Annalex: Eating pork or not circumcising boys were sins till the Church abolished these restrictions (Acts 15)

count-your-change: No. The decision was made by God and He so informed the church of His decision

The Catholic Church generally operates by the guidance of the Holy Spirit, in that matter and any other. So why do you object to my "the Church abolished these restrictions"? What is it exactly you are saying No to?

[count-your-change]

It was an angel that announced to Cornelius that the restrictions of the law had ended and thus Peter was given his vision and Cornelius guided to him. (Acts 10)
No decision on ending the restrictions of the Mosaic law (including circumcision and split hoofed non cud chewers) was made by the church and none was necessary, it was an accomplished fact.
