Lord's Day 21

54. What do you believe concerning the “holy, catholic Church”?

That out of the whole human race,1 from the beginning to the end of the world,2 the Son of God,3 by His Spirit and Word,4 gathers, defends, and preserves for Himself unto everlasting life a chosen communion5 in the unity of the true faith;6 and that I am and forever shall remain a living member of this communion.7

55. What do you understand by the “communion of saints”?

56. What do you believe concerning the “forgiveness of sins”?
