"What believest thou concerning the ‘holy catholic church’ of Christ?
That the Son of God from the beginning to the end of the world, gathers, defends, and preserves to himself by his Spirit and word, out of the whole human race, a church chosen to everlasting life, agreeing in true faith; and that I am and for ever shall remain, a living member thereof" – Heidelberg Catechism, Lord’s Day 21, Q & A 54
What is the "rock" on which Christ build His
church?
How does Christ build His church?
How does this comfort us in a day of small things?
