The greatest commandment should control all doctrines

Opening

There are doctrines defended with verses that, in practice, produce hardened people. There are systems that talk about holiness, but train contempt. There are biblical readings that preserve the phrase and betray the spirit of Christ.

This is where the greatest commandment needs to function as a criterion, not as a devotional ornament. When an interpretation or application of faith generates hatred, cruelty or dehumanization, the problem is not just a moral one. It's hermeneutic. This does not authorize disregarding historic Christian orthodoxy or abandoning the divinity of Christ, his real resurrection, or the existence of God. But it requires that all doctrine, all tradition and all practice be measured by the center that Jesus established.

If Christ is the way, the truth and the life, then loving God and neighbor is not an emotional appendage. It is the judgment on our readings.

What the biblical text says

In Matthew 22:37-40, Jesus answers the question about the greatest commandment with two quotes and a decisive conclusion. First, he quotes Deuteronomy 6:5: “You shall love the Lord your God with all your heart and with all your soul and with all your mind.” Then add to this Leviticus 19:18: “You shall love your neighbor as yourself.” And then he concludes: “All the Law and the Prophets depend on these two commandments” (Matt. 22:40).

Mark records the same logic, but with an important detail: the commandment of love appears within the confession of the Shema — “Hear, Israel, the Lord, our God, is one Lord” (Mark 12:29-30). Love for God does not appear loosely in the air; It is born from the oneness of God. The answer ends with the same emphasis: “There is no other commandment greater than these” (Mark 12:31).

In Luke 10:25-28, the person who formulates the answer is an interpreter of the Law, and Jesus confirms it: “Do this and you will live” (Luke 10:28). Soon after, the parable of the good Samaritan (Luke 10:29-37) develops the theme of neighbor in a concrete way, refusing any spirituality that protects borders and abandons the wounded.

Jesus also connects love to the public identity of his disciples: “By this everyone will know that you are my disciples, if you have love for one another” (John 13:35). In John 15:12, he resumes the commandment. And in Matthew 7:12, the golden rule summarizes the treatment of others: “Whatever you want men to do to you, you also do to them.”

Historical and theological context

The command to love God in Deuteronomy 6:5 is part of the heart of the Shema (Deut 6:4-5), the central confession of Israel. Leviticus 19:18 is already inserted in a block of instructions on community justice, honesty, care for the poor and the stranger, and rejection of revenge and resentment (Lev 19:9-18). Love, there, is not sentimentality. It is concrete fidelity to the alliance.

It is commonly understood that in Second Temple Judaism there were debates about the relative weight of the commandments. Jesus enters this environment as a Jewish teacher, but his authority is unique. Theologically, this text understands that he not only participates in the discussion: he reorganizes it based on the character of God revealed in his own life.

Church history shows the opposite risk. At different times, Christian sectors used biblical language to justify social exclusion, racism, religious persecution and abuse of authority. In these cases, the doctrine was not always abandoned; It was often applied without the restraint of the greater commandment. The result can be a merely verbal orthodoxy, accompanied by moral disfigurement.

Analysis from Jesus

Jesus did not teach love in theory. He embodied it at real cost. In Matthew 9:10-13, he eats with publicans and sinners and corrects a religiosity that protects façade purity while despising people. In Matthew 23:23, he denounces leaders who neglect “the most important things in the Law: justice, mercy and faith”. In Mark 1:40-42, he touches the leper, crossing the barrier of ritual fear. In Luke 4:18-19, he announces good news to the poor and liberation to the oppressed.

Even the passage from John 7:53–8:11, whose textual transmission requires caution, points in the same direction: Jesus prevents the execution, unmasks the manipulative accusation and, at the same time, does not call the sin irrelevant: “go and sin no more” (John 8:11).

Here it isthe criterion. If an interpretation or application of a doctrine makes us less like Jesus, it has lost its way. If it trains the community to humiliate, exclude for pleasure, treat people as disposable or turn enemies into ideological fetishes, it urgently needs to be reevaluated.

A serious objection needs to be heard: love does not mean permissiveness. Jesus does not lie, does not relativize everything and does not dissolve the truth. He calls for repentance. But his way of confronting never dehumanizes. Biblical love is not moral anesthesia; it is the holy form of truth. The test, therefore, is not whether a doctrine displeases someone. The test is whether it produces contempt, oppression, lying, violence, or dehumanization incompatible with the character of Christ.

Conclusion

The textual certainty is simple and strong: Jesus taught that loving God and neighbor is the axis on which “all the Law and the Prophets depend” (Matt. 22:40). He also made mutual love the visible mark of his disciples (John 13:35). This is not a peripheral detail. It is theological architecture.

In light of this statement, this text understands that Christian doctrines need to be judged by the center revealed in Christ. Not just for verbal precision, but for fidelity to his character. A reading that fuels hatred, cruelty or dehumanization must be reevaluated, even if it is dressed in pious language.

What doesn't remain open is whether love matters. This was stated by Jesus. What remains open is where our traditions still resist this order and prefer to protect systems, identities and powers rather than subject everything to the greater commandment. At this point, there is no need for neutrality. If Christ is the center, love is not a complement to doctrine. It's your judgment.
