“These unwritten traditions span the whole life of the Church. The veneration of saints, statuary, iconography, Church architecture, the offering of incense, the lighting of candles, the public affirmation of our faith in the Eucharist through Corpus Christi celebrations, and the crucifix at the focus of our Churches.”
Even the Catholic encyclopedia states that lighting of candles and other customs came from pagan religions.
There is no inspired architecture, veneration of saints, statuary, iconography, etc. and can’t be found before 100 ad. As such, it was not part of the Apostles tradition.
This is what happens when historical neophytes try their hand at attempting to undermine Catholicism.
The seven great letters of St. Ignatius of Antioch, written around the year 106 while on his way to Rome to be thrown to the beasts, take for granted the existence of local hierarchical churches, ruled by bishops who are assisted by priests and deacons. Ignatius, a living disciple of John the Apostle, writes that “Jesus Christ...is the will of the Father, just as the bishops, who have been appointed throughout the world, are the will of Jesus Christ. Let us be careful, then, if we would be submissive to God, not to oppose the bishop.”
Within each city there was a single church under a bishop, who in turn was assisted by priests in the spiritual realm and deacons in the administrative. The latter devoted themselves especially to alms-giving, and a striking feature of primitive Christianity is its organized benevolence. These local churches were largely self-sufficient but would group around a mother church in the region — Antioch, Alexandria, Rome — and the bishops of each region would occasionally meet in councils. But they all considered themselves part of a universal Church — the Catholic Church, as Ignatius first called it — united in belief, ritual, and regulation.
