I am more inclined to think; that when Paul was speaking here; he meant to equip Christians to withstand what this age was about to persecute them with; also he believed in the immediate return of Christ. He also understood that a single minded person could devote themselves entirely to God; more-so than a married person with children and should he/she be captured; the family would be placed in a more vulnerable, fragile situation. Also in this; he knew the people wouldn't be divided by whom to serve first - God or family. It was trying times for Christianity as many opposed the movement; lives were taken and people faced all kinds of life threatening situations. Paul was giving the listeners a picture of how it would be to be fleeing oppression, hunger and poverty. Furthermore his sermon was given in love as he knew more about the dangers that were coming; due to his experiences with the Romans, and those who persecuted him personally and the church; don't forget he himself said he was the chief sinner for he went after those who were Christians as Saul ruthlessly, fervently. For those reasons he preached on celibacy; for he knew that if they remained Pure towards God they would be strengthen as many would be needed to help the distressed widows and orphans which resulted in any part of mass persecution. The Jews and Christians of that time era had no rights; the Romans were the dictators who reigned. Paul preached celibacy knowing this would strengthen their commitment to God; keep themselves out of fleshly desires; as they would be needed to help those widows and orphans, along with other ministerial duties.
As one answer-er stated: "The end of the world is near by God's standards."
Caesar, people still rise in love; human attraction happens. Paul didn't preach this as Law. Also; most of us aren't living under those circumstances but if we were many would take heed to the wisdom and common sense of those thoughts.
Build Your House on the Rock
“Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. 25 And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. 26 And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. 27 And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.” (Matt: 7)
Jesus also knew the hurricane winds would advance; Paul acted from a spirit of love; warning people of coming dangers; how important it would be to keep your mind focused on God wanting to to equip the early Christians to withstand what that age was about to persecute them with. Many single people would be needful to help those families in dire times.
Now as to the Shaker movement:
It was a merging of both Quaker and French Camisard beliefs that created the Shakers. The Quakers were founded in England in 1652 by George Fox. Stressing the "Inner Light of Christ," the early Quakers taught that direct knowledge of Christ was possible to the individual "without a Church, priest or "book as the final word of revelation." (Thus; the Shakers made up their own set of rules; and did not follow the Biblical principles. ((which you know Caesar!))
As of 2017, the remaining active Shaker community in the United States, Sabbath-day Lake Shaker Village in New Gloucester, Maine, has two members: Brother Arnold Hadd and Sister June Carpenter. Sister Frances Carr died on January 2, 2017. Being open to individuals joining their community, the Shakers receive about two inquires a week. Their celibacy combined with external and internal societal changes resulted in the thinning of the Shaker community, and consequently many of the other Shaker settlements are now "village museums." While it's true that some of their practices revolved in the renunciation of sinful acts and that the end of the world was near - The members looked to women for leadership, believing that the second coming of Christ would be through a woman. In 1770, Ann Lee was revealed in "manifestation of Divine light" to be the second coming of Christ and was called Mother Ann.( preaching her gospel views- which weren't supported by the Bible.) By 1793 property had been made a "consecrated whole" in each Shaker community.
Shakers developed written covenants in the 1790s. "Those who signed the covenant had to confess their sins, consecrate their property and their labor to the society, and live as celibates. **If they were married before joining the society, their marriages ended when they joined.***" A few less-committed Believers lived in "non-communal orders" as Shaker sympathizers who preferred to remain with their families. The Shakers never forbade marriage for such individuals, but considered it less perfect than the celibate state. (It's obvious why this group died out.)
