U.P.C. Contradictions

The U.P.C. teaches that speaking in tongues is the necessary sign of salvation. ( their examples Acts 2:4, 10:46, 19:6 ) they take these verses out of context. Faith and sanctification is the result of receiving the Holy Spirit ( 1 Corinthians 12:3, Romans 15:16, 2 Thessalonians 2:13 ).
