Dear Davide
Warmest greetings in our Lord's name.
I don't know your circumstances but all I know is that our duty is to obey and as we look to the Lord and commit out ways to Him he guides providentially. There is one duty which is clear, that we are to belong to a sound church, and so I would concentrate in your position on finding a sound church. All other decisions should then be based around this.
If you are due to move in a year's time, could you not move to an area where there is a sound church? Why does the move have to be to another area where the church situation is the same or worse?
And your English is great for one who has not studied it formally!
