In one of Ellen G White's comments in KJV Bible on Galatians 2 she concurred with the elders in Jerusalem that the Gentiles are free from the obligations of the ceremonial law
But the three leading apostles, against whom no such prejudice existed, having themselves been won to the true position, brought the matter before the council, and won from all a concurrence in the decision to leave the Gentiles free from the obligations of the ceremonial law.
(Sketches from the life of Paul, 192-193)-6BC 1108,4)
According to the book of Leviticus animals food mentioned in the text rendered one ceremonially unclean when consumed or touched. It stands to reason that food was classified under the ceremonial law which E G White concurred that Gentiles were not obliged to keep or observe
Leviticus 11:4 NIV
The camel, though it chews the cud, does not have a divided hoof; it is ceremonially unclean for you. 5 The hyrax, though it chews the cud, does not have a divided hoof; it is unclean for you. 6 The rabbit, though it chews the cud, does not have a divided hoof; it is unclean for you. 7 And the pig, though it has a divided hoof, does not chew the cud; it is unclean for you. 8 You must not eat their meat or touch their carcasses; they are unclean for you.
The book of Hebrews further reiterate that food and drink were ceremonial laws until the time of reformation(new order)
Hebrews 9:8 NIV
The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still functioning. 9 This is an illustration for the present time, indicating that the gifts and sacrifices being offered were not able to clear the conscience of the worshiper. 10 They are only a matter of food and drink and various ceremonial washings—external regulations applying until the time of the new order
Having said that why then do the SDA still maintain that this prohibition concerning these foods is still binding?
