My husband and I are looking for a new church. We seek to find a church that we can become members in. We recently attended a church of the Nazarene. Both of us really liked it however, we don't know much about it. I have spoken with the pastor and was very pleased. The day after we attended the church a member brought us baked bread and information about the church along with a letter saying thanks for attending. The pastor called my home and left a home and work number to reach him if we had any questions of needed a prayer request. Overall, we felt welcome and comfortable.
My only questions are;
What is denominational?
I have always belonged to non-denominational.
Is a denomination bad?
I understand that the Nazarene church came about by a man, is this bad?
Do they have different beliefs than a non-denominational church?
I feel like these are elementary questions, but I do not know about denominations. I don know that the church made us feel welcome. Please help me understand this more. I am really confused by outside influences and what they think. (Family mostly filling my mind with non-sense.) Any information would be helpful. Thank you all who can help me understand better.
