God the Holy Spirit always comes to individuals. Also in our account [Acts 2] it is individuals who are filled with the Spirit. It is over each head that the flame of fire flickered and each individual spoke. But when God the Holy Spirit comes to individuals, he places them in fellowship. Its as Luther says so beautifully in his catechism: “I believe that I cannot by my own understanding or effort believe in Jesus Christ my Lord or come to him, but the Holy Spirit has called me through the gospel, enlightened me with his gifts, sanctified and kept me in the faith just as he has called gathered and enlightened the whole Christian church on earth, sanctified and kept it in the one true faith." The two go together. The Holy Spirit has called me to faith. Nobody else can believe for me. But my faith is not without the faith of others, "just as he calls, gathers and enlightens the whole Christian church on earth and keeps it united in Jesus Christ in the one true faith." This close connection between the faith of the individual Christian and that of the whole church has been forgotten in the modem world in both the catholic and evangelical churches. We have forgotten that we aren't in the church just as individuals, each with his own private thoughts. We are members together of a congregation joined together in prayer and supplication and in the confession of the one true faith. It all goes together - the unity of love and the unity of faith. Where one is missing, the other is also going to be missing. This idea of Pentecost of the early church, has probably been preserved best by the Eastern Church. It is the practice in every service to speak the creed as follows: The priest says at the altar "Let us love one another that we may confess in the unity of faith." The choir continues the sentence "the Father and the Son and the Holy Spirit." Then the Nicene Creed is said.
