Dear Nikodim,
I am sorry if our article upset you.
Even if Matryoshka dolls were really inspired by a Japanese pagan toy (although this is only a popular belief), is this really anything new? Does this present any danger to Christianity, which has always transformed pagan holidays and symbols, filling them with pure, God-pleasing meaning (for example, the Cheesefare Week).
With the quote “all in One, and One in all” we did not seek to appeal to any heretical creeds. Our idea is that the Lord is present among the believers (Matt. 18:20) and unites them in the Eucharist; allowing them to abide in Him, He Himself abides in them (John 6:56).
This idea is also reflected in the prayer of St Basil the Great, read in the canon before Communion: “…But trusting in thy loving-kindness I come unto thee who has said: He that eateth my Body and drinketh my Blood shall dwell in me and I in him…” Thus, we all live only by One God, by His will and His great humility, making Him present through Eucharist even in the smallest of us.
Peace of Christ be with you!
