I indeed thought about it. The first quote warns against sex outside of its bounds, which all should agree is wrong.
However, the White quotes I raised were not about this problem, but dealt with the marriage relation.
The second talks of “sinful excess”.
And as to "sinful excess", where does the Bible say frequent sex in marriage is sinful? That is what you have utterly failed to demonstrate.
It doesn't have to say it is sinful. But James 4:17 does reveal that when we go against what we know to be good, it becomes sin to us. Paul and Peter also emphasized "temperance" (Gal 5:23; 1 Peter 1:6). This envelops everything. Ellen White is giving us "additional" details not in the Bible, and that is exactly what a prophet is for. To provide and zero in on additional details.
The fact that Paul says that there should be a time that we "refrain for a time", is in harmony with Sister White:
"Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency." (1 Cor 7:5)
Paul seems to indicate here that it is good to take breaks.
The Bible DOES say that if you withhold from one another you LACK self control in I Cor. 7.
You need to make your biblical case for too much sex being evil in marriage.
First and foremost, does the Bible say what you just said?
I don't see where the Bible says what you said.
You have Ellen’s advice wrong here. She does not at all counsel 3 or 4 times a week.
Her whole view centers around her idea of vital force. She sees us giving account of our vital force, and that it is depleted through “indulgence”.
She does not say how long. But 3-4 times a week is just a sensible guess based on judgment.
Very few feel it to be a religious duty to govern their passions. They have united themselves in marriage to the object of their choice, and therefore reason that marriage sanctifies the indulgence of the baser passions. Even men and women professing godliness give loose rein to their lustful passions, and have no thought that God holds them accountable for the expenditure of vital energy, which weakens their hold on life and enervates the entire system. (Testimonies, Volume 4, p. 472)
She feels that sex depletes energy that God gives them.
The point is that there are those who do not marry on the basis of true love, but lust. And they marry simply to gratify their sexual passions rather than based on true love. But, assuming 2 people do love eachother, and it is a God-ordained marriage, it is better to marry than the two to burn. This is excellent counsel from Sister White. There are husbands and wives who over-indulge in sexual intercourse and deplete the vital forces. This is no different than gluttony with eating good food.
Can you demonstrate that men and women suffer from depletion of vital force through sex? Can you demonstrate that the Bible warns against this thing we are to be accountable for?
Another quote that talks about how she feels this leads to premature death, and loss of health.
Science tells us how the world is millions of years old, and cannot prove the earth was created. Scientists also said it could not rain, but they were wrong.
A number of scientific studies today I believe have an agenda to corrupt humanity, and so they will produce reports stating that you can have sex as much as you want and there are no consequences to health.
I believe what Sister White says by faith.
A miserable existence is entailed upon so large a class that death to them would be preferable to life; and many do die prematurely, their lives being sacrificed in the inglorious work of excessive indulgence of the animal passions. Because they are married, they think they commit no sin. {SA 171.1}
Can you demonstrate that people die prematurely due to too much sex? And where does the Bible warn of this?
But would you be able to prove it? There are millions of people that die all the time, and there is no way to prove exactly why they got sick and died. There is no way to always prove exactly why they died of heart-failure. There is no possible way to prove this, but Ellen White is showing one of many causes here. She is not talking against sex, but "excessive indulgence". The quotes you site only prove my point.
Ellen White was proven right on many points, but science is still ongoing, and changing, and still has a way to go to catch up (if ever). Simply because some current "scientific research" may disagree with Sister White is a lame, ridiculous, unacceptable excuse to disqualify her as a prophet.
Let the Christian wife refrain, both in word and act, from exciting the animal passions of her husband. Many have no strength at all to waste in this direction.
While she councils against excess in some places, here she speaks of many who have "no strength at all" to "waste" in this direction. So here she suggests they should not waste ANY vital force, because they have already wasted too much. She is certainly not endorsing 3 or 4 times a week here, but in some cases none.
Excellent counsel! She simply means do not waste necessary strength that we might need for other work--as in excess. She's not saying we can't expend affordable strength to what God has allowed.
That is a far cry from Proverbs:
Pro 5:18 Let thy fountain be blessed: and rejoice with the wife of thy youth.
Pro 5:19 Let her be as the loving hind and pleasant roe; let her breasts satisfy thee at all times; and be thou ravished always with her love.
I disagree. 24/7 is not being spoken of here. It's speaking in terms of a mutual life-time bond. Once your wife is yours, she is always available to you. But God expects us to use temperance, as in every good thing.
Why does the Bible say they are to be satisfied and rejoice, and Ellen White says many have no strength to "waste" this direction..
Because you are misunderstanding her.
There are two very different underlying views of sex here. And her council that some have NO strength is certainly not encouraging 3 or 4 times per week.
On the surface it may appear that way, but I don't believe this is a correct assessment. You can read this into it, but I don't think it's accurate.
But beyond that we have other evidence of what she and her husband thought on the subject. James published Solemn Appeal Relative to Solitary Vice, and the Abuses and Excesses of the Marriage Relation.
This book included Ellen White’s commentary on these issues, but also put supporting informant from health reformers that the White’s agreed with. Here we see more specific council as to frequency. Here is one such statement from the work:
But for light-built, fine-skinned, fine-haired, spare-built, sharp-featured, light-eyed persons, of either sex, to indulge, even in wedlock, as often as the moon quarters is gradual but effectual destruction of both soul and body; because they already work off vitality faster than their feeble vital apparatus manufactures it. This excess of expenditure over supply occasions their sharpness. A surplus would render them fleshy. Now to add the most powerful drain of all to their already sparse supply, must sooner or later, according to their vigor of constitution, render them bankrupts of life.
But Ellen White did not write this, and where is there proof that she endorsed this?
Here again we see this reference to the depletion of vital force. Here we are told to indulge as often as the moon quarters is destruction of soul and body. That is not three or four times a week.
Excess of anything depletes the vital forces. Even excess of staying up late. It wears you out and can exhaust. There are numerous people who live a sexually promiscuous life, and they are very unhealthy people.
Another quote from the same work:
Whoever indulges often, and weekly is often, in wedlock or out of it, will experience an unnatural heat, tension, tenderness, irritation, swelling, perhaps soreness, in these organs, of course resulting from their inflammation.
Can you demonstrate harmful inflammation from weekly intercourse in marriage? Does the Bible warn against such?
Yet this is advice that the Whites placed along-side Ellen’s advice on “marital excess”.
So your view of 3-4 times a week rather than every night sex also fails to deal with the real view they held.
They thought every “indulgence” “wasted” energy that God had given for other things, and you were to be held accountable for your expenditures.
Once again, Ellen White did not write what you quote, and there is no proof that she "endorsed" it.
