'Doctrine' in the Bible

“Go, stand and continue to tell the people in the temple [courtyards] the whole message of this Life [the eternal life revealed by Christ and found through faith in Him].”

saying, “We gave you strict orders not to continue teaching in this name, and yet you have filled Jerusalem with your teaching and you intend to bring this Man’s blood on us [by accusing us as His murderers].”

So in the present case, I say to you, stay away from these men and let them alone, for if this plan or action is of men [merely human in origin], it will fail and be destroyed;

Now those [believers] who had been scattered went from place to place preaching the word [the good news of salvation through Christ].

Now the apostles and the believers who were throughout Judea heard [with astonishment] that the Gentiles also had received and accepted the word of God [the message concerning salvation through Christ].

When they had spoken the word [of salvation through faith in Christ] in Perga, they went down to Attalia.

And they spoke the word of the Lord [concerning eternal salvation through faith in Christ] to him and to all who were in his house.

but since it is merely a question [of doctrine within your religion] about words and names and your own law, see to it yourselves; I am unwilling to judge these matters.”
