John Trapp on 1 Corinthians 1:2

Verſe 2. Called to be Saints] i. e. Either ſuch as are ſanctified by habituall infuſion, or ſuch as are ſanctified by baptiſmall profeſſion only, that are in Covenant with God by ſacrifice, Pſal. 506. and are in Chriſt, though they bear no fruit, Ioh. 15.2. Theſe two ſorts of Saints make up a true viſible Church.

With all that in every place] The Apoſtles then wrote not their Epiſtles for the particular uſes of thoſe times only, as the Jeſuites will have it.
