16 Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them. 17 And when they saw him, they worshipped him: but some doubted. (Matthew 28:16-17 KJV)
William Burkitt’s Commnetary
The meeting of our Saviour and his apostles upon a mountain in Galilee, was an appointed and general meeting. The mountain is supposed to be that near Capernaum, where he made that famous sermon, called, The sermon on the mount: and the meeting is supposed to be appointed as a general rendezvouz for confirming the faith of all his disciples in the certainty of his resurrection. Possibly our Lord appointed this place in Galilee, so far from Jerusalem, that his disciples might without danger come thither to see their Saviour alive again, after his crucifixion.
This is judged to be that famous appearance of which St. Paul speaks, When he was seen of above five hundred brethren at once. 1Co 15:6 And those who say him worshipped him, who before had doubted.
Learn hence, That when faith is once satisfied, and sees Christ to be God, it engages the soul to worship him. Divine worship is due to Christ upon account of his divine nature. No creature can be the object of divine worship, therefore they who worship Christ by praying to him, and yet deny him to be God, are certainly idolaters. If Christ had an angelic nature, that had not made him capable of divine worship: for adoration is founded only on divinity, and what is but human or angelical, is not adorable.
