I was unable to read all the posts of this thread entirely but in whatever I read I found so much misinformation that I cannot keep silent on this.
The forms of both private and general confessions have existed and still exist in the Armenian Church since ancient times.
Today the practice of private confession in our Church mostly depends on the parish and the clergy. I live in Armenia and many believers here, including me, have their confessor fathers to whom they confess privately. But to take Communion one needs to take part also in the general confession. St Gregory of Tathev (14-15th centuries) has numerous sermons on private confession, and he mentions also the general form of confession which was read both after the private confession, and separately. He says there are minor sins that do not necessarily need to be confessed privately (like a bad word, thought, inappropriate laugh etc), and such sins can be forgiven also only through the general confession. However, for other, more serious sins, one MUST confess to the priest privately. There are sermons on confession (private) also by other Armenian Fathers. And not only written in those ancient times but also, for example, in the beginning of the 20th century. One of the sermons of Fr Emanuel Nazareants, published in the beginning of the 20th century and republished in Armenia some years ago, speaks on PRIVATE confession. The most extensive catechism of the Armenian Church written by Arshak Ter-Mikelyan and published first in the 19th century and republished twice in recent times, also speaks about PRIVATE confession in the Armenian Church.
This shows that both forms of confession in the Armenian Church have been used since old times and at least until the beginning of the 20th century. And if today the practice of private confession is not spread widely, it is never a rule in the Armenian Church and private confession is always welcomed today, especially in some parishes of Armenia. If this is not so in the diaspora and some parishes of Armenia, it's the fault of the clergy and NOT a RULE.
