The context of those passages, as I recall, is basically that “Jesus is gonna come back any second now, so don’t bother with worldly concerns like marriage and making babies. Just devote your life to being a good Christian and leave the fornicating to the heathens, unless you absolutely can’t live without getting laid on the regular.” It’s hard to understate the degree to which the early church was basically a doomsday cult. They were certain that the Rapture was going to happen in their lifetimes, and that short time horizon had a big impact on how they thought their society should be organized.
My high-school friend group adopted “it goes” from our French class (“Comment ça va?” “Ça va!”, roughly meaning “How goes it?” “It goes!” being the common neutral greeting taught in French classes) and I slightly resent it being described negatively here.
