During his address to the congregation that included the royal family and world leaders, the Archbishop recalled the promise the Queen made on her 21st birthday to dedicate her life to service - "Rarely has such a promise been so well kept. Few leaders receive the outpouring of love we have seen."
But a key quote from his speech has caused discussions online on whether he was throwing shade at Johnson.
"Those who serve will be loved and remembered longer than those who cling to power and privilege are long forgotten," the Archbishop said.
This quote was shared by The Guardian's Political Editor, Pippa Crerar and has since gone viral with over 13,000 likes and thousands of reactions from people who have speculated who the Archbishop was referring to.
\u201cArchbishop of Canterbury, Justin Welby: \u201cThose who serve will be loved and remembered longer than those who cling to power and privilege are long forgotten\u201d.\u201d
In his Easter sermon, the Archbishop said the plans raised "serious ethical questions" and added: "Sub-contracting out our responsibilities, even to a country that seeks to do well, like Rwanda, is the opposite of the nature of God who himself took responsibility for our failures."
Johnson hit back as sources close to the then-prime minister said he accused the senior clergyman of being "less vociferous" in their criticism of Russian president, Vladimir Putin.

Some felt that the Archbishop's quote could ironically also be implied to himself and the royal family.
\u201cMany are applauding this line but I can\u2019t help but think celebrating the Queen and criticising those who \u201ccling to privilege\u201d might have worked better at a funeral that didn\u2019t have a diamond-encrusted crown.\u201d
\u201cI see why people think this is shade at the Tories, but... this is a bishop of a vastly wealthy church that has ever decreasing followers talking about an unelected, undemocratic monarch who heads a system based entirely on privilege and birthright, so I'm not overly impressed.\u201d
