Like I have said, I think all angels have graces. Just the more higher ranked, Cupids, Average Angel foot soldiers, Seraphs, Archangels etc, state what the Connection to Heaven gives. However, Eric Kriple said that, normally a cast oout or fallen angel even the Archangels cannot return to Heaven without it. He used this to explain why, Lucifer didn't/couldn't just go into Heaven after Sam released him after season 4. And why he used his last restort vessal nick. However, he also use it had something to do with Michael as well. This was among the numerous interviews with him, before his leaving the series to Sera Gamble.

But, I think the Archangel's graces are even more powerful and Holy than any other rank of angels. And don't require the connection to Heaven for any direct power or for more power from like average angels. And this is to why, they are numerous times more powerful than even Seraphs the second stronger angelic rank seen thus far.
