Bishop Strickland has been a public critic of the Bishop of Rome, in direct opposition to Jesus' High Priestly Prayer

This canonical line of reasoning reflects the technical distinction between different levels of the Catholic Church's Magisterium (teaching authority).
Under Catholic canon law, an encyclical focused on social, political, or technological ethics—such as Magnifica Humanitas—falls under the ordinary Magisterium. Because it addresses contemporary socio-ethical guidelines rather than dogmatically defining an unchangeable article of faith (such as the Divinity of Christ or the Trinity), it does not carry the weight of infallibility. Consequently, bishops and theologians possess a canonical framework to voice scholarly reservations or pastoral concerns, provided it is done with due reverence for the papal office.

However, this canonical allowance sits in deep tension with the spiritual and theological critique  regarding Jesus' High Priestly Prayer for unity (John 17:21: "that they may all be one"). This clash highlights two fundamentally different views on the role of a bishop and the nature of church hierarchy:

The Resistance Argument: Protecting the Church's Core Mission
Prelates who voice strong, public resistance to documents like Magnifica Humanitas often justify their stance through a specific ecclesial logic:
• Resisting Secularization: Traditionalist critics frequently argue that when the papacy focuses heavily on global policy issues—like regulating artificial intelligence, taxing Big Tech, or addressing climate change—it risks reducing the Catholic Church to a mere political NGO or a secular humanitarian agency.
• Prioritizing the Supernatural: From this viewpoint, a bishop’s primary canonical and spiritual duty is the salvation of souls and the defense of core dogma. They argue that public dissent on non-dogmatic, prudential matters is a necessary act of "filial correction" to keep the Church anchored in its supernatural mission rather than temporal geopolitics.

The Institutional Critique: Eoding Papal Authority and Unity
Conversely, canonists and theologians aligned with the Holy See argue that public, adversarial resistance directly undermines the visible unity of the Church:
• The Duty of Religious Submission: Canon 752 of the Code of Canon Law states that while not an assent of faith, a "religious submission of the intellect and will" (religiosum intellectus et voluntatis obsequium) is still required for teachings manifested by the supreme magisterium of the Pope.
• Scandal and Division: Critics argue that when high-profile prelates aggressively oppose a papal encyclical in the public square, it causes immense scandal among the faithful. By transforming pastoral guidance into a ideological battleground, this public defiance actively opposes Christ’s prayer for institutional and spiritual unity, fracturing the global flock into polarized political factions.

Ultimately, while canon law provides the technical space to debate the prudential applications of Magnifica Humanitas, the public manner in which this resistance plays out continues to severely strain the theological bonds of communion between dissenting bishops and the Bishop of Rome.
