The time is now, the place is here. Stay in the present. You can do nothing to change the past, and the future will never come exactly as you plan or hope for.
The problem is that no ethical system has ever achieved consensus. Ethical systems are completely unlike mathematics or science. This is a source of concern.

A person who believes that Elvis is still alive is very unlikely to get promoted to a position of great power and responsibility in our society. Neither will a person who believes that the holocaust was a hoax. But people who believe equally irrational things about God and the bible are now running our country. This is genuinely terrifying.
The Christian view that all intercourse outside marriage is immoral was, as we see in the above passages from St. Paul, based upon the view that all sexual intercourse, even within marriage, is regrettable. A view of this sort, which goes against biological facts, can only be regarded by sane people as a morbid aberration. The fact that it is embedded in Christian ethics has made Christianity throughout its whole history a force tending towards mental disorders and unwholesome views of life.
