The Parental Duty in Catholic Education
When Catholic parents entrust their children to schools established by the Church, they rightly expect that the instruction provided will be faithful to Catholic doctrine. This duty extends not only to the moral content of teaching but also to the subjects taught. The Church has always upheld a clear and comprehensive body of doctrine, transmitted from the apostles, against which mere human theories or social trends hold no weight. Yet in many Catholic schools today, especially in the West, civil authorities have pressured educational institutions to adopt programmes of so-called “sex education” that conflict with both divine and natural law.

The Primary Educators of the Child
It is indeed necessary that children, at an appropriate time, be instructed about the realities of human reproduction and the moral obligations that accompany these truths. However, the responsibility for this instruction belongs to parents alone. This duty is given directly by God and cannot be rightfully taken over by the state, by educators, or even by bishops. Parents may, for practical reasons, delegate certain aspects of education—such as mathematics or science—to others who possess the requisite expertise, but this delegation always proceeds from the authority of the parents and remains under their supervision.¹

The Limits of Delegation
The Church teaches that parents, strengthened by the grace of the sacrament of marriage, have the responsibility and privilege of evangelising their children and forming them in virtue.² Teachers, priests, and catechists share in this mission only insofar as parents freely authorise them to assist in what properly belongs to the family. Certain subjects—such as the training in personal virtue, purity, and moral discernment—cannot be delegated. The state may require that citizens be educated for civic duties, but its jurisdiction ends where the intimate and moral formation of the child begins.

The Superiority of the Family over the State
The Church firmly rejects any attempt by governments to replace or control parental authority. Leo XIII warns that when the state “sets aside the parent and sets up a State supervision,” it violates natural justice and destroys the structure of the home.³ The Catechism reminds us that the family is the primary school of solidarity and virtue, and that parents must protect their children from “compromising and degrading influences.”⁴ Indeed, Leo XIII affirms that the family is “a society very small, one must admit, but none the less a true society, and one older than any State.”⁵

This principle is also recognised in civil law. The European Convention on Human Rights explicitly protects the rights of parents to educate their children in conformity with their religious and philosophical convictions (Article 2, Protocol 1) and recognises family life as a sphere of privacy and protection against state interference (Article 8). These provisions reflect what the Church has always taught—that the family possesses rights anterior to the State, grounded in natural law and divine order.

Moral and Practical Formation
Parents naturally instruct their children in language, manners, modesty, and virtue. To neglect these areas or to surrender them to institutions is to abdicate a sacred trust. Among these responsibilities lies the duty to educate children about human reproduction and sexuality—matters that require both moral maturity and personal sensitivity. No classroom teacher can judge with precision the appropriate time or method for every child, since these depend upon individual development, temperament, and grace.

Cautions on Implementation and Parental Vigilance
In recent years, Catholic-approved Relationships and Sex Education (RSE) programmes—such as Life to the Full by Ten Ten Resources—have been widely adopted, reportedly by the majority of Catholic schools in England and Wales.⁶ While the Catholic Bishops’ Conference of England and Wales (CBCEW) and the Catholic Education Service (CES) state that RSE should promote chastity, dignity, and respect for life, traditional Catholic commentators have expressed serious concerns about the way such programmes are implemented.

Traditionalists, including the Society of Saint Pius X (UK District), warn that some RSE programmes risk undermining the parental role and present sexuality in an overly naturalistic or psychological manner, divorced from the supernatural virtue of chastity.⁷ They argue that materials sometimes prioritise “risk mitigation” or “self-esteem” over moral formation and fail to acknowledge humanity’s wounded nature and need for grace.⁸ The danger, they note, is that RSE lessons become exercises in information rather than formation—transmitting biological facts without grounding them in moral and theological truth.

Scholars examining traditional Catholic resistance to sex education likewise record the same concern: that Catholic schools, even when guided by Church documents, can inadvertently “supplant rather than supplement” the parental role.⁹ In mixed or collective settings, discussions of sexuality risk becoming occasions of curiosity or embarrassment rather than of virtue. The Church has consistently warned against “collective or public sex education” that ignores the discretion and modesty owed to each child’s stage of development.¹⁰

When RSE Becomes a Contravention of Parental Rights
In principle, Relationships and Sex Education can be delivered within Catholic schools without violating parental rights. However, in practice, such rights are frequently compromised or constrained by state mandates and the secular assumptions underlying modern educational frameworks.

RSE contravenes parental rights when it:

• introduces sexual or moral content without parental knowledge or consent;
• normalises behaviours contrary to Catholic moral teaching, such as contraception, cohabitation, or same-sex acts;
• pre-empts parental judgment about a child’s readiness for such instruction;
• or discourages withdrawal through social pressure or institutional policy.

These practices directly violate both the natural-law right of parents to form their children in moral truth and the legal right protected under Article 2 of Protocol 1 of the European Convention on Human Rights, which guarantees education in conformity with parental convictions.¹³ They also conflict with the Church’s explicit teaching that “it is incumbent on parents to strain every nerve to ward off such an outrage, and to hold exclusive authority to direct the education of their offspring.”¹²

The Poison of Naturalism
The recurring fault identified by traditional Catholic critics is the persistence of naturalism—the belief that moral formation can be achieved through reason or social conditioning alone, without recourse to divine grace. As Pius XI explains, such approaches “refuse to recognize the inborn weakness of human nature” and disregard “the means of grace” by which purity is preserved.¹¹ The Church teaches that because fallen man bears the wounds of original sin—ignorance, malice, weakness, and concupiscence—mere human instruction cannot preserve chastity without spiritual formation and sacramental life.

Parental Vigilance and Partnership
For this reason, parents must be vigilant regarding what is taught in the name of “Catholic education.” They should review all RSE materials used by their children’s schools, exercise their right to consultation and, if necessary, withdraw their children from any lessons inconsistent with Catholic doctrine. True partnership between home and school means not merely compliance or trust, but collaboration under parental authority. The right to know, to approve, and to object is not only a civil entitlement but a duty arising from the parental vocation.

A Call to Restore Catholic Integrity
Catholic schools must remember that they exist not to reflect the prevailing culture but to redeem it. To comply with statutory RSE obligations while neglecting the Catholic vision of purity and grace is to betray their mission. The teaching of human sexuality must always be presented as part of the call to holiness—never as a technical or social matter detached from faith. Where government policy or secular expectations conflict with divine law, Catholic schools must stand firm in fidelity to Christ and to the Magisterium.

As Pius XI urged, parents must “strain every nerve to ward off such an outrage” as the corruption of family life by worldly influences and to “hold exclusive authority to direct the education of their offspring.”¹² In our time, this vigilance is not merely prudent; it is indispensable to preserving innocence, virtue, and faith in the hearts of children.
