...is the consistent teaching through the known world.
Shortly after Pentecost he apostles left Jerusalem and began sharing
the gospel throughout the Roman empire and beyond. They went to modern
India, the West-most points of North Africa, and well into Europe
(modern France or further). Yet, they all taught the same message.
We've all probably played a game
of telephone where each person secretly passes a message but by the
time 4 or 5 people have passed the message vital information has been
left out or erroneous information has been added. How much more would
we expect this human error effect in the apostles' teaching when they
had such little communication with each other?
On one hand,
this shows that the Holy Spirit must have, and must still be, guiding
the Church but on the other hand it shows that these simple fishermen
must have had intense instruction from the risen Jesus between Easter
and Pentecost. After the crucifixion they didn't have the theological
sense to understand that the messiah must suffer yet after Pentecost
they were able to consistently preach a complex doctrine of salvation
through Jesus' crucifixion and resurrection. Where did they gain such
Looking at Luke 24 and the road to Emmaus story
gives a worthy answer. Just as our children are first baptized and
confirmed when they're ready to be spiritual adults so too Jesus
embraced the apostles right after his resurrection but formed them from
theological infancy to adulthood before sending them out at Pentecost.
This is yet another reason Catholics believe in the resurrection.
