Help discerning 1 Corinthians 5:9-12

I have a mother that bears the name of a "brother"

Here Paul instructs us to not even assosiate with those who continue in willful sin, idolatry

She is one of the ones who are bearing the name of a brother, she is not of the world

When paul says to not even eat with such (assosiate) how do you understand this? Is this specific to just your church? Is this specific to friends or also family

Love to hear your thoughts :)
