During one of my classes this past weekend on the NT church, good brother Alex Soares commented that Paul said in Ep 5.25, “Christ loved the church and gave himself for her.” That puts the church squarely at the center of God’s plan.
The church is the object of Christ’s love and sacrifice. When the question is asked, “What did Christ accomplish by his death?”, the church must be mentioned. How then can one talk about Christ’s sacrifice to non-Christians and not mention the church, as some propose?
That same day or the next, someone read from Ac 20.28, where Paul speaks of “the church of God that he obtained with the blood of his own Son.” The text reinforces the Ephesians passage.
Those who urge leaving out the church when speaking of the gospel have an agenda that is not reflected in Scripture. Either that, or they are ignorant parrots of progressive mouths.
