Who christens Little John?

From the text:

Then when the feast was done Will Stutely spoke up. "It is now time, I ween, to christen our bonny babe, is it not so, merry boys?" And "Aye! Aye!" cried all, laughing till the woods echoed with their mirth.

"Then seven sponsors shall we have," quoth Will Stutely, and hunting among all the band, he chose the seven stoutest men of them all.

"Now by Saint Dunstan," cried Little John, springing to his feet, "more than one of you shall rue it an you lay finger upon me."

But without a word they all ran upon him at once, seizing him by his legs and arms and holding him tightly in spite of his struggles, and they bore him forth while all stood around to see the sport. Then one came forward who had been chosen to play the priest because he had a bald crown, and in his hand he carried a brimming pot of ale. "Now, who bringeth this babe?" asked he right soberly.

"That do I," answered Will Stutely.

"And what name callest thou him?"

"Little John call I him."

"Now Little John," quoth the mock priest, "thou hast not lived heretofore, but only got thee along through the world, but henceforth thou wilt live indeed. When thou livedst not thou wast called John Little, but now that thou dost live indeed, Little John shalt thou be called, so christen I thee." And at these last words he emptied the pot of ale upon Little John's head.
