In this episode, Pastor James Brown Jr. begins a series of podcasts to  explain the identity, mission, and vision of Holy Trinity Reformed  Church by answering the questions "who are we?" and "what makes us  different?"

"The  catholic or universal church, which is invisible, consists of the whole  number of the elect, that have been, are, or shall be gathered into  one, under Christ the Head thereof; and is the spouse, the body, the  fullness of him that filleth all in all. The  visible church, which is also catholic or universal under the gospel  (not confined to one nation, as before under the law), consists of all  those throughout the world that profess the true religion; and of their  children: and is the kingdom of the Lord Jesus Christ, the house and  family of God, out of which there is no ordinary possibility of  salvation. Unto  this catholic visible church Christ hath given the ministry, oracles,  and ordinances of God, for the gathering and perfecting of the saints,  in this life, to the end of the world: and doth, by his own presence and  Spirit, according to his promise, make them effectual thereunto. This  catholic church hath been sometimes more, sometimes less visible. And  particular churches, which are members thereof, are more or less pure,  according as the doctrine of the gospel is taught and embraced,  ordinances administered, and public worship performed more or less  purely in them. The  purest churches under heaven are subject both to mixture and error; and  some have so degenerated, as to become no churches of Christ, but  synagogues of Satan. Nevertheless, there shall be always a church on  earth, to worship God according to his will. There is no other head of the church but the Lord Jesus Christ. Nor can the pope of Rome, in any sense, be head thereof." –Westminster Confession of Faith, Chapter 25, Of the Church
