Now, Greece's parliament has approved a bill granting same-sex couples the right to a civil union, becoming one of the last European countries to give them legal recognition after years of opposition from the influential Orthodox church.
Mr Tsipras said the bill gives same-sex couples "equal rights in life and death", terminating a practice of "backwardness and shame" for Greece.
Greece had been condemned for anti-gay discrimination by the European Court of Human Rights in 2013, after gay couples were explicitly excluded from a prior civil unions law in 2008.
The law was supported by 193 lawmakers out of 249 present, with 56 voting against it.
It's like a Christmas present for our LGBT friends in Greece, congratulations guys! Remember, love is love no matter what.
