The Westminster Larger Catechism (1648)

10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:

22 And hath put all things under his feet, and gave him to be the head over all things to the church,

23 Which is his body, the fulness of him that filleth all in all.

16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.

52 And not for that nation only, but that also he should gather together in one the children of God that were scattered abroad.
