A church is a business. Most people don't look at it that way but they are, especially if they have schools to run as mine did. It's a business, they want money and some are shameless in asking for it.
A church is also made up of good and bad people as any business is.
Those people in the church that are your friends can still be and you can still see them as you choice.
You might not worship in the same building or have the same beliefs but friendships should not if they are true need to be of the same faith or belief.
Many people have changed their minds on the churches teaching as we have grown in technology and wisdom.
Most people I have found only follow some not all of their churches teachings. I know at this point of no Catholics who do not practice birth control that is forbidden by the church. That does not make them bad Catholics it makes them wise people who only have children they can afford or want.
The Lutheran church I was a member at said the earth was only 5 thousand years old. THAT WAS THE DUMBEST THING I EVER HEARD!
And yet........................... When the pastor said this I saw heads nodding believing............... I was speechless and then after the shock I figured they were too far gone to talk sense into so I left them to their ignorce and keep my mouth shut. I truly wanted to throw a fossell at them but I figured it would go over their head..............
I am still friends with members of my former church, three people in fact. One Dr and two nurses, only one the LPN is still there the other two have moved on.
But that is really my point, you have not lost friends, you are in the process of making new ones and of learning and growing and letting your soul sour. I hope you enjoy this very exciting and rewarding time in your life.
