Will I actually be condemned if I do not go to a Church, Synagogue, Mosque, etc.?
Hell no! Or no Hell even. Individuals are not judged for eternity on such things.
And think about this, where were the churches, etc. during the times of Adam and Eve, Abraham and Sarah, and so on...?
Moses was raised as an Egyptian, do you think Moses was condemned because of this? No.
These places honestly need money for the most part, so they use scare tactics to get people to attend many times. Scare tactics of "You will go to Hell" and that kind of stuff. Not true.
But truthfully, Almighty (God) created everything because He wished not to be so lonely. Almighty cares very much about His creations, both great and small. And since Almighty created, He also knows that people (humans, etc.) are not born with knowledge. As such, Almighty realizes people can get some strange as well as some very wonderful thoughts. And these thoughts can be very wonderful sharing experiences throughout eternity. Some thoughts can also be horrible too. Each individual is unique as Almighty is unique Himself.
Individuals are judged throughout eternity based on their behaviors towards others, not on quoting verses out of books or any of that stuff. And definitely not based on "How many times did you go to Church, Synagogue, Mosque, etc.?" either.
After being in bondage for over 400 years, and the freeing by the deliverer / prophet Moses, the Hebrews were told to keep a day of rest (Sabbath) in remembrance of Creation, but also of being in bondage. No rest for slaves. When Ieshua (Jesus) was caught working on the Sabbath and such, there was much concern among the 'leaders', yet the leaders themselves had already sold out to the Romans when Ieshua did this. Sadly, the jewish leaders were allowing bazaars and tax collecting and such in the temples which was not to be allowed. A lot of turmoil to be sure around the early AD period. Still much turmoil to this day.
But whether Christian, Muslim, Jew, Gentile, Infidel, Heretic, Meek, Butthole, smart, stupid, deaf, dumb, blind, atheist, agnostic, pagan, witch, warlock, whatever, it is behavior traits that decide. And above all, it is Almighty's (God's) decision as Almighty created all, He also takes responsibility for all as well.
