The Apostles’ Creed’s confession of faith “in the Holy Spirit” is followed by its confession of faith in “the holy catholic Church.” Here, the word ‘catholic’ refers not to the Roman Catholic Church, but to the universal church of the Lord Jesus Christ. 
The Apostles, who believed in the baptism and blood of Jesus, witnessed Jesus Christ to many people on the Day of Pentecost. Then, they came to repent, and also believed in the baptism of Jesus, and become saints, and thereby the Church was established for the first time. Like this, those who believe in the works of the Holy Spirit also believe in the Church, which has been established by these works of the Spirit.
