If Jesus and that apostles ate blood at the last supper they were sinning against the laws of God and therefore Jesus would not have been sinless nor would He have been able to save anyone.
That is your opinion and it is wrong. It is a denial of the Word of the Lord. It is a denial of The Truth.
Your opinion is false and either heresy or incredulity. Although you may be in the stage of apostasy.
What Is Heresy?
Heresy is an emotionally loaded term that is often misused. It is not the same thing as incredulity, schism, apostasy, or other sins against faith. The Catechism of the Catholic Church states, “Incredulity is the neglect of revealed truth or the willful refusal to assent to it. Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and Catholic faith, or it is likewise an obstinate doubt concerning the same; apostasy is the total repudiation of the Christian faith; schism is the refusal of submission to the Roman Pontiff or of communion with the members of the Church subject to him” (CCC 2089).
