In necessariis unitas, in non necessariis libertas, in utrisque caritas.
In essentials, there should be unity; in non-essentials, liberty; in both cases, charity [love].

This maxim is sometimes presented as, In necessariis unitas, in dubiis libertas, in omnibus caritas which is translated as, "In essentials, there should be unity; in doubt, liberty; in all things, charity (love)."

This is incorrectly attributed to St. Augustine. Its origin has been traced to an admonition intended to bring peace into the church, given by Rupertus Meldenius to the theologians of the Augustinian confession (ca. 1625).

It is also said to be the motto of the Christian Church, Disciples of Christ.
