1 Corinthians 7:14
Clementine Vulgate · Berean Standard Bible
sanctificatus est enim vir infidelis per mulierem fidelem, et sanctificata est mulier infidelis per virum fidelem : alioquin filii vestri immundi essent, nunc autem sancti sunt.
For the unbelieving husband is sanctified through his believing wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be unclean, but now they are holy.
