I believe in the Holy Spirit, the holy Christian Church, the communion of saints.
Through this article the Holy Spirit, with His office, is declared and shown: He makes people holy [1 Cor. 6:11].
The "holy Christian Church" a "communion of saints," both expressions, taken together, are identical.
This is the meaning and substance: I believe that there is upon earth a little holy group and congregation of pure saints, under one head, even Christ. This group is called together by the Holy Spirit in one faith, one mind, and understanding, with many different gifts, yet agreeing in love, without sects or schisms. I am also a part and member of this same group, a sharer and joint owner of all the goods it possesses. I am brought to it and incorporated into it by the Holy Spirit through having heard and continuing to hear God's Word, which is the beginning of entering it. In the past, before we had attained to this, we were altogether of the devil, knowing nothing about God and about Christ. So, until the Last Day, the Holy Spirit abides with the holy congregation or Christendom. Through this congregation He brings us to Christ and He teaches us the Word. By the Word He works and promotes sanctification, causing this congregation daily to grow and to become strong in the faith and its fruit, which He produces. (paragraphs 34, 35, 47, 51-53)
