You might find the information and discussion contained in this thread of interest in finding out more on Eastern Orthodoxy:
There area a few more things to bear in mind with Eastern Orthodoxy, terms and ideas can be understood differently, also there are different approaches in Eastern practice and worship to Western, to quote a section from Andrew Louth’s book Introducing Eastern Orthodox Theology which I quoted in that thread:
Rather, it’s distinctiveness is to be found in the way in which the traditional faith of Christians is upheld among the Orthodox. For Orthodoxy sees its faith as expressed, and tested, in prayer and worship.
Many Christians would assent to that, but there have been influential movements within Western Christianity that have sought to express Christianity in some comprehensive philosophy - the scholasticism of the Western Middle Ages is a striking example - or make some particular doctrine the article by which the Church stands or falls - as Luther did with the doctrine of justification by faith. In reaction against that, in the West, other movements have sought to reduce Christianity to a non-dogmatic devotionalism - implicitly in certain strands of Western medieval mysticism, or explicitly in pietism. But for Eastern Orthodoxy it is in prayer and worship of God that our faith is defined and refined: a God who created this world and loves it, whose love is expressed in identifying himself with his creation, and especially the human creation, made in his image, through the Incarnation and the cross, a love that is manifested in its transfiguring power through the resurrection. The centrality of prayer and worship prevents us from narrowing down our faith to some human construction, however magnificent.
If there is any reason why Eastern Orthodoxy has found this way of confessing the Faith, it could be because of the way Eastern Orthodoxy has led through persecution and martyrdom: in every century there have been Christians of the Orthodox communion who have faced persecution - throughout the whole Christian world in the first centuries, and then while living under Islam, and in the last century atheist communism. In all these centuries it has been faithfulness to prayer and worship of the Church that has enabled the Church to survive. Often it was only in gathering together for prayer and worship that Orthodox Christians were able to express their faith, and frequently such gathering together was subject to harassment - a harassment sometimes as severe as any persecution. And they found that that was enough, that faithfulness in prayer and worship, in celebrating the divine liturgy, in belonging to the saints of all ages and joining our prayers with theirs, and then living out, as fully as they could, lives formed by that worship: all this proved to be in truth the touchstone of their faith. The experience of martyrdom and persecution has been the crucible in which Orthodox Christians have found their faith refined.’
Louth, A. ‘Introducing Eastern Orthodox Theology,’ (on my mobile (cellphone) kindle app 6% location 214-232 - it feels wrong to cite without page numbers lol, I feel a negative mark coming ).
This is a good link for giving an understanding (at least the latter section of the article) of the Orthodox understanding of Tradition (though I think with some points on Papias the author could do with reading John Bauckham’s Jesus and the Eyewitnesses, that would end up I think strengthen his position, but it would differentiate the point slightly). The article is written strongly from an Eastern Orthodox specipective, and in relation to Protestant tradition of sola Scriptura, which whether someone agrees or not I think will give a starting insight into the concept of apostolic Tradition, useful for reading other things from the Orthodox tradition.

This video by John Behr can also be useful in some concepts of the general ground and initial hypothesis or grounding understanding in Orthodoxy.

None of this is comprehensive, and perhaps the thread I began and give you more insights, the Orthodox Church does regard itself as founded and keeping the deposit of the apostolic faith, and that this has been keep and guided through the Holy Spirit, which is their understand of Jesus promise in John and some of Paul’s promises, and expressed in worship in the liturgy, the Scriptures, the Fathers and in the bishops and in the conciliar agreements most clearly represented in the 7 Ecumenical Councils. That might give a start, getting a book like Louth’s Introducing Eastern Orthodox Theology or reading the Divine Liturgies of St John Chrysostom and St Basil the Great can also help, but it can be a difficult question to answer without being partisan over whether the Orthodox or another Church reflects the true inheritance of the early Church, the best thing to do is familiarize yourself with Orthodoxy and take your understanding from there.
