Greek English New Testament
This is an edition of the New Testament you can read and search online.
The texts used are, the original Greek New Testament of the Ecumenical Patriarchate of Constantinople (the most authoritative version), and the King James English translation.
The texts are presented side by side, which is great if you want to have a look at the original when you read the translation, or if you learn Greek.
The edition is further enhanced with Sacred Icons from Athos Holy Mount.
