In every modern legal system, freedom is guaranteed to every person and is considered a fundamental human right. Freedom is studied from different perspectives, and this paper will explore the concept of freedom from various angles, its historical development, as well as its possible impact on the sacrament of marriage. The Code of Canon Law from 1983 pays special attention to the general and fundamental obligations and rights of all members of the Catholic Church, among which it regulates the right to freely choose one's state of life (can. 219). The choice of one's state of life is a choice between secular, clerical, or religious life, and between marriage and celibacy. Therefore, such a choice must be the result of a free, conscious, and considered decision. The freedom of choice is sacred, and as such, it is respected and legally protected. It excludes coercion and violence, as well as any act that could prevent or condition it. Marriage as a sacrament and contract in the Catholic Church represents a holy and permanent union, rooted in God's love and grace, aimed at a common life directed toward the good of the spouses and the birth and upbringing of offspring. Due to the immense importance of this fundamental institution of society, Canon Law regulates how the impediments of abduction (can. 1089), coercion and grave fear (can. 1103) affect the valid contracting of marriage and what legal-pastoral means are used to protect a person's freedom.
