You can not bind,cast,pull down nor defeat or have any spiritual confrontation with powers of your foundation, father's house until what's connecting you with them is broken and destroy completely.
The meeting signifies : lineage,inherited practice, idolatry or bloodline.
You must get out of that before you can bind them and separate yourself totally from inherited idolatry or infliction/affliction of your father's house :foundation.
Your prayer point should focus on :
Every link,bond, lineage, bloodline and inherited idolatry,evil practice of my father's house, foundation weakling and rendering my salvation,heaven powerless, I renounce u today,Break by fire.
Bible ref : 2cor 5:17
Bless you.
