Sunetheia denotes an established practice, whether a community practice, an idol-connected habit, or a Passover release practice.

The attested verses use the term for an established practice: a practice rejected among the assemblies, a continuing habit connected with an idol, and a customary Passover release.

1. Established practice or custom · dominant

   In 1 Corinthians 11:16, the accusative singular form occurs in the statement that the assemblies have no such practice; the APB renders the clause "we have no such custom." In John 18:39, the nominative singular form introduces a Passover release practice; the APB renders "there was a custom among you that I should release one man to you at the Passover."

   1 Corinthians 11:16John 18:39
2. Continuing habit associated with an idol · occasional

   In 1 Corinthians 8:7, the dative singular form stands in the clause about some who eat as idol-offered because of their continuing association with the idol. The APB renders this as "because of their custom with the idol until now."

   1 Corinthians 8:7

In the Anselm Project Bible: The APB uses "custom" in all three verses, presenting either a community practice, an idol-connected habit, or a Passover release practice. These renderings confirm the clauses' overall presentation rather than isolate every contribution of the term.
