Continue to pursue the “Catholic Catechism”. It fits folks who need something to do. The “do” Jesus was talking about clearly is not something an astronaut would have to “do”, even if he would be gone for years. Again, no frequency, no specificity, no schedule to keep...unless you have bought the Romanist line. Then there are rules galore, many things to do, or hell to pay. You stay there...I’ll go with Jesus.

So to summarize, biblical Christianity does have something to “do” but it "is not something an astronaut would have to “do”.
Is it something people on, say, maybe, Earth would have to do?
