Eu tenho harmoniaO amor e a verdadeEu tenho a justiçaDa Santíssima Trindade
First of the four
The hymn quoted above is the clearest statement the tradition has of its own ethical vocabulary: harmony, love and truth, and then justice, all four attributed to the Most Holy Trinity and all four received rather than achieved alone — o Mestre tem a força, ele é quem me dá, the Master has the force, he is the one who gives it to me. The order of the words is the order of the 1916 motto of the Círculo de Regeneração e Fé, with justice added from the parent order's formula.
A state to be reached
The doctrine describes harmony as marking a more evolved state of being, arising from a kind of resonance between a person's own vibration and that of their surroundings. It is treated as an achievement rather than a given — something a person grows into rather than simply possesses. That framing is consistent with the practice it sits inside: works that run for many hours in ranked formation, where keeping together is not a metaphor.
Harmony among people
In this teaching, harmony among people is described as the path by which deeper mysteries of life and a sense of universal solidarity become understood. Rather than treating harmony as a private attainment, the doctrine ties it directly to how people relate to and understand one another — which is why the same word names both an inner condition and the discipline of a room full of singers staying in time.
Padrinho Sebastião's hinário gives it a still plainer image: o amor é o trono da harmonia — love is the throne of harmony, the seat it rests on.
