Luke 24:19

And He said unto them, What things? Christ constrains them to open their grief and to confess their doubts as to His resurrection.

And they said unto him, concerning Jesus of Nazareth. They acknowledge Him, says Bede, to be a great prophet, but they do not speak of Him as the Son of God, either because their faith was imperfect, or because they feared lest they might fall into the hands of the persecuting Jews. For they knew not with whom they were speaking and therefore concealed what they believed to be true. Because they say (verse 21) that they trusted that it had been he, as being the Messiah and the Son of God, which should have redeemed Israel.

Mighty in deed and in ward. So should every Christian be, especially those who have devoted themselves to a religious life, or have been called to any office in the Church. What they preach they should perform, and teach first by example and then by word.
