Apparently, both? I am not comlpletely sure what is meant by "selections" used in the following paragraph. However, it is clear that not all of the Apocrypha is contained in the BCP.
from here:

"The Apocrypha is a collection of books written by people of the Old Covenant. The Articles of Religion note that these books may be read "for example of life and instruction of manners," but are not used to establish any doctrine (Art. VI, BCP, p. 868). Selections from the Apocrypha are included in the BCP lectionaries for the Holy Eucharist and the Daily Office."
and
"All persons ordained as bishops, priests, or deacons in the Episcopal Church must solemnly declare at their ordination that they "do believe the Holy Scriptures of the Old and New Testaments to be the Word of God, and to contain all things necessary to salvation. . .." (BCP, pp. 513, 526, 538). Selections from scripture for the Episcopal Church's services of the Holy Eucharist and the Daily Offices are provided by the lectionaries of the BCP (pp. 889-1001)."
I am sorry, I forgot that not all BCP are the same, and that not everyone is going to have one handy. MY (my husband's actually - though I use it too) BCP has the Bible contained therein (1928 with Apocrypha).
