Some people in churches particularly the conservative ones think we are doomed for everything. To tell you the truth when I see people at church they seem normal nothing in your post would fit the bill of them they go to church and do normal church stuff.
I am however different. I don't mind burning incense at home here it smells nice and relaxes me after work i gave up alcohol and use that in place to trigger relaxation. As for mystical I defiantly seek to know god as closely as I can if that means long periods of prayer and quiet moments that may resemble eastern religions meditation after i read my bible, I don't care it draws me closer to god and feels great. I probably am a bit mystic . Being this way has only drawn me closer to god. I figure god made all things the incense too lol. Who cares who else uses it too it don't really matter at all.
I am not entirely sure about the term mystic Christian i think it is a catholic one.
I would place a higher risk to believers on what comes out of the televisions in our lounge rooms for corrupting and compromising Christians in churches. Every single day there is exposure to soft porn and its teaching you to be greedy and covet products in search of happiness and fulfillment. The ultimate modern idol worship device. lately i have noticed it telling our youth its ok and acceptable to pursue bisexuality and follow the current young role models of today. That TV It takes your focus off god like nothing else we have.
You bring up some very good issues .... I too burn incense, not everyday, but I enjoy the aroma. I do need to provide good ventilation though, because of my allergies.
The problems with Mysticism are very complex and not easy to explain in just a few sentences, or even a few paragraphs. I'm sure that many people who are involved with some aspect of Mysticism are not going to hell, just because they read the mystics, burn incense, or meditate, read their Bible for hours on end ....
There are real dangers though that many people are not aware of and do not understand. I've been involved with cults, the occult, and seen demons, and have seen and experience the destruction that deceptions from the enemy (Satan, the Father of Lies) causes, including much damage to my family and many friends.
Yes, Catholicism has been infected with Mysticism, but it goes much deeper than the Catholic church ..... There are demonic practices that some people get involved with when practicing Mysticism, which opens doors to the demonic spirits.
Many elements of Mysticism are not compatible at all with Christianity and the Bible. The Bible clearly teaches that we are all sinners. Mysticism would have us search for the inner light, or divine essence of God that is supposedly already in us, which is unbiblical.
Romans 3:23 (King James Version)
23For all have sinned, and come short of the glory of God.
The only way that we can find peace with God, is salvation through Jesus Christ, not by emptying ourselves and our minds, and seeking some mystical inner light, or whatever people want to call it (divine something).
1 Timothy 2:5 (King James Version)
5For there is one God, and one mediator between God and men, the man Christ Jesus.
