As others have said, it can be summed up in two words:
Of necessity.
Of course it’s not just them. All the dozens (hundreds?) of groups that have been founded over the centuries who claim that they are the “true”, “restored” church claim the same thing, for the same reason, as stated above. I just ran into another one today that I had not heard of: the “World Wide Church Of God”. Nice name. Unfortunately for them, that position was already filled 2,000 years ago by Jesus Christ, and there is only one Body of Christ, who is the one Bride of Christ, who He will wed on the Last Day. Apparently they have roots in the Seventh-Day Adventists.
[19] So then you are no longer strangers and sojourners, but you are fellow citizens with the saints and members of the household of God,
[20] built upon the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone,
[21] in whom the whole structure is joined together and grows into a holy temple in the Lord;
[22] in whom you also are built into it for a dwelling place of God in the Spirit.
For no other foundation can any one lay than that which is laid, which is Jesus Christ.
The foundation has already been laid by Christ, with He Himself as the cornerstone, and has been built up for 2,000 years by the Holy Spirit. No one can “uproot” this divine structure. Christ is the “wise builder” who “built his house upon the rock; and the rain fell, and the floods came, and the winds blew and beat upon that house, but it did not fall, because it had been founded on the rock.”
He said so: “And I say to you, you are Peter and on this rock
I will build My Church.” One can only build another structure next to it and then * claim* that the new structure is the “true” building, but, as said before, Christ’s building’s foundation has
already been poured and the building itself is nearing completion. As it says in Psalm 46, “the most High hath sanctified his own tabernacle. God is in the midst thereof, it shall not be moved.” Its “mortar”, if you will, is Love, the Holy Spirit, who is God, who is Love. The foundation was poured and solidified 2,000 years ago, and then Paul and all the Saints (and saints) built upon it and were built
into it. In my mind I imagine Christ as the supervisor, directing all the goings-on involved in construction, with the Holy Spirit “effecting” the individual bricks (i.e. us) being sanctified, molded into proper form, and inserted into the structure according to the Divine plan (which would be the “blueprints”), with the Father looking on from above, blessing all the work that is being done.
It’s a
divine project, *therefore *it can be said that God sees everything that he is making, and it is very good.
God bless
