Abrahams (b. 1622) intensified the _seeker_ aspect of the Amsterdam group, emphasizing the view that the existing Church, even in its best form, is only an interim-Church with no saving sacraments and no compelling authority. His position is expressed in the highly important "Nineteen Articles" which he, and his fellow-believer, David Spruyt, drew up in 1658, and in the further Exposition _Nader Verklaringe_ of 1659. These documents present the apostolic pattern or model as the ideal of the visible Church for all ages. There neither is nor can be any other true Church. It is essentially a Church managed, maintained, and governed through "gifts" bestowed by the Holy Spirit, and in this Church each spiritual member takes his part according to the measure of his special "gift." This pattern Church, however, {121} _fell away_ and became corrupted after the death of the apostles, and instead of this glorious Church an external Church was established, claiming to possess authoritative officials, saving sacraments, and infallible doctrines, but really lacking the inward power of the apostolic Church, no longer following and imitating Christ, on the contrary adopting the world's way and the world's type of authority, and destitute of the very mark and essence of real Christianity, _the spirit of love_. Through all the apostasy of the visible Church, however, an invisible Church has survived and preserved the eternal ideal. It consists of all those, in whatever ages and lands, who have lived by their faith in Christ, have kept themselves pure and stainless in the midst of a sinful world, have practised love, even when they have received the buffets of hate, have lived above division and schism and sect, and have steadily believed that their names were written in heaven and that their Church was visible to God, even though none on earth called them brother, or recognized their membership in the body of Christ. Some time, in God's good time, that invisible Church, which no apostasy has annulled or destroyed, will become once again a visible Church, equipped with "gifted" teachers and with apostolic leaders as at the first, beautiful once more as a bride adorned for her husband, and powerful again as the irresistible sword of the Spirit.
