In brief, a biblical divorce is a divorce that occurred because the offending spouse committed sexual sin with someone else (bestiality, homosexuality, heterosexuality, or incest) or because the non-Christian spouse obtained the divorce.

The “wives of deacons” interpretation seems to be more likely, as it would be unusual for Paul to give qualifications for deacons in verses 8-10 and 12-13, with qualifications for deaconesses in between.
There are definitely some who will have nuanced and different opinions based on their views on sacramental theology and the theology of marriage.
