⁴⁶ And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,
⁴⁷ Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.

God ADDS those who are saved to the CHURCH.
Being saved and being in the church are the same thing.
