I had prepared a lengthy reply, but lost connection and my post. Here, briefly I will re-visit this post.
To summarize, each protestant makes his own decisions, has his own guided conscience in such matters of church attendance. It is a cultural phenomenon in the South (where I lived for 30 years) to go to church on Sunday to show you were a good, upright Southern Christian. There’s no denying that.
However, I personally for 30 years (as a Southern Baptist) believed it was sinful to miss church services and to not even tithe 10%. It is a Biblical principle to rest one day of the week and honor God. It is also an Old Testament principle to tithe from one’s income. I have believed these things the majority of my life. I do not now.
So, it really depends on the individual, whether Baptist, Lutheran, Methodist, what have you. One’s consciousness of sin is individual at its nature. It cannot be forced upon a person to admit sin in their life. As Scripture indicates, part of the role of the Holy Spirit has been to convict the world of sin.
And, therefore, my belief based on that Scripture that the Holy Spirit alone can show a person their sin. No matter how much pleading, beating, killing we do in this world - we cannot change another person or nation or race or religion or make them see some things that we personally see. They must allow themselves to be open to change and knowledge.
To make general statements concerning acknowledgement of sin in individuals and attach those statements to their church affiliation is irresponsible and stereotypical. We should not make such statements. We have no polls, interviews, evidences to support any claims (that I know of). I have personal experience and others have their personal experiences. And those experiences are necessarily the whole truth.
Peace…
