Who said the Church didn’t exist yet?
Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that by the mouth of two or three witnesses every word may be established.’ And if he refuses to hear them, tell it to the
church. But if
he refuses even to hear the church, let him be to you like a heathen and a tax collector.
Matthew 18:15-17
The Apostles who asked the question about His coming and the end of the age are the foundation of the Church.
And when He had called His twelve disciples to Him, He gave them power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease.
Now the names of the twelve apostles are these: first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus; Simon the Cananite, and Judas Iscariot, who also betrayed Him. Matthew 10:1-4
- He gave them power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease. Now the names of the twelve apostles
Matthew 10 and 18 were before Matthew 24.
