It is not "sacramental entrepreneurs," but "sacramental minions" that our Lord desires. He desires those who have been taught to treasure everything He has commanded and will faithfully carry out His will and His commands as He has clearly given them to us in the Scriptures. For His Word and the Sacraments that He instituted are God's instruments through which He sends His Holy Spirit to work faith in those who hear the Gospel when and where it pleases Him.
The problem of upstarts pushing forward with startups in the church is not new. De-emphasizing the commands of God in favor of the ideas and thoughts of men is as old as the Church itself. Adam and Eve were induced by Satan to set aside God's Word and eat of the forbidden fruit. And, the Pharisees and teachers of the Law in Jesus day were regularly called out by Jesus for setting aside the Word of God for the traditions of men.
GOD is the one and only real "Sacramental entrepreneur." GOD has established the church it continues to be grown, sustained, nurtured and nourished by Him through the means that He has established for that purpose.
