Its not good to minimize an Apostle by saying they are a Church planter. They are more than that. They are representatives of Jesus Christ. Yes they will establish Churches. They will teach true doctrine and will mark anyone who teaches differently as did the founding Apostles.
They will do mighty signs and wonders by the power of the Spirit. I dont know anyone doing that today but they may be out there somewhere. I know that they will exist in the end time in "Mystery Babylon".
At the destruction of Babylon we read this:
18:20 Rejoice over her, thou heaven, and ye holy apostles and prophets; for God hath avenged you on her. Rev. 18:20
So we know for sure in the last days Apostles will be ministering in Babylon. I could not say with surety they exist right now but am praying for the Father to raise them up.
