Does your translation say Aramaic? My NKJV says Hebrew.
If you translation also says Hebrew and it is your church that says it really means Aramaic I would ask why your church would do that.
That's what you get for reading KJV...it kees you misinformed because it is not onyl a bad translation, but its out of context. Maybe that's why the Protestants love it so much.
Read bible copmmentaries and discover the world. In reference to the Greek word Habrais used in Act 26:14: "Hebrew, the Hebrew language, not that however in which the OT was written but the Chaldee, which at the time of Jesus and the apostles had long superseded it in Palestine" [Blue Letter Bible, Crosswalk NT Greek]
"'Chaldee' or 'Chaldean Aramaic' used to be common terms for the Aramaic of the Chaldean dynasty of Babylonia. It was used to describe Biblical Aramaic, which was, however, written in a later style. It is not to be confused with the modern language Chaldean Neo-Aramaic." [Aramaic Language, Wikipedia]
