I can understand why the Canons of Dort are not the object of much consideration in PCUSA circles nowadays. It did, however, come to my attention that some old translations of the render the 5th article of the second main point as saying:
"the promise of the gospel is that whosoever believes in Christ crucified shall not perish, but have eternal life. This promise, together with the command to repent and believe, ought to be declared and published to all nations, and to all persons promiscuously and without distinction, to whom God out of His good pleasure sends the gospel".
More recent versions read: "without differenciation or discrimination". We sure can use some of that missional "promiscuity" in our congregations today!
