Peter calls himself a bond-servant and apostle (missionary) of Yeshua Messiah. He tells us to whom he is writing. He is writing to those who “have received a faithfulness of the same kind as ours by the righteousness of our Elohim and and Savior, Yeshua Messiah.”
Paul designates those who came out of idolatry and could not eat meat because of the imagery of that meat being an animal sacrificed to an idol, as being “weak” in faithfulness. He was speaking of how we need to be patient and non-judgmental of those who are weak in their faithfulness in this manner. While there is nothing Scripturally wrong with eating meat, eating meat appeared to be an act of idolatry to those who were weak. He tells us to bear the weaknesses of those without strength. We are not to just live for ourselves.
