Justin is a person. He does not represent 'Eastern Catholicism'; he writes as a person being formed in an Eastern Catholic Church, specifically the Greek-Catholic
Church of Kyiv, otherwise known as the Ukrainian Greco-Catholic Church. He is lead editor of Theological Reflections on the Hong Kong Umbrella Movement (Palgrave, 2016). His blog is literally a 'log on the web' of his current personal reflections about whatever he is thinking about and praying over, which for him are basically the same thing.
