What does that have to do with Apostolic Succession? Re: the referenced passage speaks nothing of the Apostles continuing to be actively involved in the Church.
The Apostles continue to play a role in the Church, unless you think that a foundation has no role in the life of a house ... but they are alive ... cf. Jn 8:51, Rev 7:15
And since I am living by the Scriptures, I can only follow leaders that were appointed through the Apostles ... and must follow the Pillar of Truth(1 Tim 3:15), as the Israelites did (cf. Ex 13:20-22) ... the Catholic Church being the Church described in Holy Writ ... cf. Is 2:2, Mt 5:14...
Oral Tradition"? The text says that the Thessalonicans faithfully preached the Gospel, which Gospel is written in Scripture.
The Scriptures cannot testify to themselves, any more than Christ can (cf. Jn 5:31) ... and as John and the Father testified to Christ, so do the Church Fathers, inspired by the Spirit (cf. Mt 16:19, Jn 14:26) testify to the Scriptures, their Canon and meaning ...
... but the reformers ...having tried to separate the authority of the Bible from the Biblical Church ... were not of one mind ... Cf. 1 Cor 1:10, Phil 2:2 ...
What "sounded forth" is said to have been "the word of the Lord" which again is the Gospel and that which pertains to it.
right, and this Gospel is the Written and Oral Tradition ... cf. 2 Thes 2:15; 3:6; 1 Cor 11:1-2, 16, 23, 34)... while most were illiterate ... and the Canon was not completed for decades after Pentecost (nor the Canon discerned for centuries), even as the Gospel was being preached in its fulness (cf. Acts 5:20) ...
