And I also tell you, [although] you are Peter [i.e., a stone], it is on this rock [i.e., the truth you have just confessed] that I will build my church and [not even] the gates of the unseen place of departed spirits will win out over it [i.e., all efforts to stamp out the church by killing Christians will fail].

And if he refuses to listen to them [i.e., the witnesses], explain the [whole] matter to the church [i.e., probably a specially called meeting of mature Christians to resolve the matter]. And if he refuses to listen to the church also, [i.e., to acknowledge his sin and repent of it], consider him like an [unconverted] Gentile or tax collector [i.e., do not have fellowship with him].
