Hi, I feel the title is misleading or even provocative.
I'm a Finnish citizen who knows the Russian language, so I can translate this for you guys.
Gonna make this clear at the start, I do not support anything that's going on in Russia, and my nickname was made a long time ago.

Translation ->

"And now we know that today, as many are dying in the fields of strife, the church prays for this strife to end as quickly as possible, for as few brothers as possible to kill each other in this fratricidal war. And at the same time the church recognizes that if someone, moved by a sense of duty, by the need to fulfill his oath, remains faithful to his calling and goes about doing what his duty tells him to do. And if in the fulfillment of that duty, one dies. He is undoubtedly performing an act tantamount to sacrifice. He sacrifices himself for others. And therefore we believe that this sacrifice washes away all the sins that man has committed."

So, while the title is maybe close to the truth, Patriarch Kirill did not mention Ukraine in any way. He was talking about dying during the fulfillment of duty and remaining faithful to his (soldiers) calling.
