Apostolic doctrine means the counsel of apostle.
Apostle is a noble model of the early church. When Holy Spirit came upon the disciples of Lord Jesus Christ, they began to speak with other tongues as the Spirit gave them utterance. When this sound occurred, the multitude came together and were amazed because everyone heard them speak in his own language. Though they were chosen and predestined by God, others mocked at them saying that they were blabbering under the influence of wine. Even today there are some supposedly devout Christians who sing of giving a million praises but when they see some true Christian saying a few praises, they call them Pentecostals and they begin to revile and ridicule it as Pentecostal doctrine.
