Unbiblical and Inconsistent Practices of the Church

1. Why does the church worship on Sunday, when the seventh day was established forever?
There is no biblical support for Sunday worship; it is a tradition of the Catholic Church which Protestants accept.
2. Why do many evangelical churches deny that baptism is essential for salvation, when the New Testament clearly teaches that it is? Mark 16:16; Acts 2:28; Acts 2:41; Acts 22:10 + Acts 9:6 + Acts 22:16; 2 Corinthians 5:17 + Romans 6:3-6
3. Why do some churches object to wine since the Bible indicates that it is a gift from God (Psalm 104:14-15)? See also, for example, Jeremiah 13:12, Joel 2:19, Deuteronomy 14:25-26, Isaiah 25:6, Deuteronomy 7:13.
How can they continue to object even when they acknowledge that Jesus turned water into wine? Is this anything more than a holdover from prohibition?
In fact, the Bible promotes drunkenness in Proverbs 31:6-7. 4. Why does the modern evangelical church embrace the extra-biblical doctrines of "having a personal relationship with Christ," having a "quiet time," "journaling," and the necessity of belonging to an "accountability group?"
Doesn't the church understand its own religion?
Why is it caught up in pop-religion?
If these are not really doctrines of the church, then why is there social pressure to conform?
5. Why does the church teach tithing for Christians, when it is only commanded of Old Testament Israel?
Why didn't Paul teach tithing to the New Testament church when he had the opportunity to (2 Corinthians 9)?
6. Why do some churches ignore controversial teachings in the Bible, such as speaking in tongues, baptism for the dead, the requirement for women to wear head coverings and to remain silent, the identification of the "sons of God" in Genesis 6, the necessity of poverty in order to follow Jesus (Luke 14:33), etc?
Doesn't the Holy Spirit reveal the true meaning of these passages to believers?
If so, why do sincere believers come to opposite conclusions on their own, and why aren't they able to come to agreement when they dialog with each other?
Surely, Jesus is with them to guide them when two or three are gathered together in his name, isn't he, even if they misapprehended the Spirit's guidance when they were on their own?
7. Why must Christians resort to divination (looking for "guidance," looking for "doors of circumstance to open or close," etc.) if the Holy Spirit dwells within them?
What is the benefit of an indwelling Holy Spirit if it doesn't manifest itself in day-to-day living, and it has to be coaxed into revealing God's will in major decisions?
8. Why do Christians pray about whether to marry someone, when Paul says that if they want to get married they should just do it (1 Corinthians 7)?
9. Why does the evangelical church rail against one-world government, since they say it is God's plan as revealed in Revelation?
How can they justify speaking and acting against God's revealed plan?
