The Dorian invasion is a concept devised by historians of Ancient Greece to explain the replacement of pre-classical dialects and traditions in southern Greece by the ones that prevailed in Classical Greece. The latter were named Dorian by the ancient Greek writers, after the Dorians, the historical population that spoke them.
In the 80’s many people refused to live there because of the weather conditions. It was too hot for the crops to survive, so in turn they would have no food to eat.
These were the essentials in the first century church: the communion supper was observed (Acts 20:7; 1 Corinthians 11:25–26), prayers were offered up (1 Corinthians 14:15–16), songs were sung to the glory of God (Ephesians 5:19), a collection or offering was taken (1 Corinthians 16:2), and the Scriptures were read, preached and taught (Acts 20:7; Colossians 4:16; 2 Timothy 4:2).
I do not think he listed all in one passage, but he did let the churches know throughout his letters what they needed to do to hold a worship service. (the biblical passages you see, Acts was not written by Paul but it narrates his part of his life and ministry from chapters 9 thru 28).
They are important because besides praising God passionately, their faith was shared with others and more people were been converted to Christianity, so they needed to be nurtured spiritually to grow in their faith and know God better with the help of the church leaders through the Scripture.
Hope it helps! If you have another question, comment this answer. I’d be more than glad to help.
The North had a population of 22 million people against the 9 million in the South (of whom almost half were slaves.)
The North was more industrial and produced 94 percent of the USA’s pig iron and 97 percent of its firearms. The North even had a richer, more varied agriculture than the South.
The Union had a larger navy, blocking all efforts from the Confederacy to trade with Europe.
The Confederacy hope that France and Britain would come to their aid due to their need of cotton, but these countries had enough cotton and a bigger need for Northern corn.
The North controlled both the shipping and railroad avenues, allowing them to trade and to get supplies fairly quickly.
The Union had more support: four slave states still remained loyal and not everybody in the 11 Confederate states were on the Confederate side. There were still plenty of people in the South that supported the Union.
Many slaves fled to the Union armies, providing even more manpower.
The South squandered their resources early in the war by focussing on conventional offensives instead of non-conventional raids on the Union’s transportation and communication infrastructure.
Lee’s offensive war strategy had a high cost in casualties, destroying a large part of the Confederate army.
