We come to a brief and interesting exposition on I believe/we believe:
83. The confession of faith is complete only in reference to the Church. All the baptized individually proclaim the Credo, for no action can be more personal than this. However, they recite it in the Church and through the Church, because they do so as members of the Church. ‘Credo’ and ‘Credimus’ necessarily imply each other. (cf. Catechism 166-67; Catechism 196.) In fusing his confession of faith with that of the Church, the Christian is incorporated into her mission: to be the “universal sacrament of salvation” for the life of the world. He who makes the profession of faith takes on responsibilities that not infrequently provoke persecution. In Christian history the martyrs are proclaimers and witnesses par excellence. (cf. Redemptoris Missio 45)
