Can. 208 From their rebirth in Christ, there exists among all the Christian faithful a true equality regarding dignity and action by which they all cooperate in the building up of the Body of Christ according to each one’s own condition and function.
Can. 209 §1. The Christian faithful, even in their own manner of acting, are always obliged to maintain communion with the Church.
Can. 212 §1. Conscious of their own responsibility, the Christian faithful are bound to follow with Christian obedience those things which the sacred pastors, inasmuch as they represent Christ, declare as teachers of the faith or establish as rulers of the Church.
§3. According to the knowledge, competence, and prestige which they possess, they have the right and even at times the duty to manifest to the sacred pastors their opinion on matters which pertain to the good of the Church and to make their opinion known to the rest of the Christian faithful, without prejudice to the integrity of faith and morals, with reverence toward their pastors, and attentive to common advantage and the dignity of persons.
Can. 225 §1. Since, like all the Christian faithful, lay persons are designated by God for the apostolate through baptism and confirmation, they are bound by the general obligation and possess the right as individuals, or joined in associations, to work so that the divine message of salvation is made known and accepted by all persons everywhere in the world. This obligation is even more compelling in those circumstances in which only through them can people hear the gospel and know Christ.
§2. According to each one’s own condition, they are also bound by a particular duty to imbue and perfect the order of temporal affairs with the spirit of the gospel and thus to give witness to Christ, especially in carrying out these same affairs and in exercising secular functions.
Can. 227 The lay Christian faithful have the right to have recognized that freedom which all citizens have in the affairs of the earthly city. When using that same freedom, however, they are to take care that their actions are imbued with the spirit of the gospel and are to heed the doctrine set forth by the magisterium of the Church. In matters of opinion, moreover, they are to avoid setting forth their own opinion as the doctrine of the Church.
