Yes and you know why The Orthodox Church is not as far vast as The RC? It is Not so easy to grow when your Muslim rulers won’t allow you to evangelize or even ring a Church Bell.
The Christian evangelists of the early centuries were not so inhibited from evangelizing under the threat
of persecution. That is,in part,how the early Church grew in the first place – through martyrdom.
Another reason why The Roman Catholics tortured and forced The Indians in Latin America to become Christians.
The Catholics who tortured the Indians and forced them to convert did not have the approval of the Rome to do so.

We did not torture The Slavs we gave them a choice.
The Slavs were not regarded as sub-human like the Indians were. Also,at the time of the conversion of the Slavs,the Eastern church was in communion with and under the ecclesiastical authority of Rome. Saints Methodius and Cyril were loyal to Rome,and Methodius was made Archbishop of Pannonia by the pope. So the conversion of the Slavs was not an accomplishment of the Orthodox Church,since there was no such entity at that time.
