The Biblical Doctrine of the Church is so multifaceted that it can hardly be exhausted in one passage of Scripture, one podcast episode, one Sunday School lesson, one sermon, or even a seminary education. The doctrine of the Church is deeply rooted in multifaceted motifs and theologies that its exploration begins in this life and will continue on throughout eternity. 
In broadest terms, the "Church" refers to the whole body or number of believers that have been, are, or shall be recipients of mercy and grace through Jesus Christ, whether they are in heaven or on earth, whether from Old Testament times or from New Testament times and forward. The point is that anybody truly saved by grace has efficaciously been summoned from this sinful state and gathered into one new body under Christ.
Today's episode scratches the surface on the spiritual dynamic that gave birth to the Church and ensuing spiritual antithesis that was realized after Genesis 3:15.
