Stop shilling your garbage.
But I'll entertain you anyway.
- The image for the filioque is not very correct. It shows two processions, or a procession from two principles. Catholics believe in one procession from one principle, "the Father and the Son."
- Eastern Catholics use leavened bread.
- Orthodox do keep consecrated gifts for later, but only for the Liturgy of the Pre-sanctified Gifts (which is only served during Lent).
- The video implies that hosts used for adoration aren't later eaten. That is wrong.
- Toll houses are not "like Purgatory but much worse". Toll houses are before the particular judgement, an Orthodox Christian can fail to pass through them and go to Hell. Purgatory is after the particular judgement, a Catholic in Purgatory will necessarily be saved.
- Some Orthodox parishes (Greek and Antiochian in my experience) use an organ for the Liturgy.
- Similarly, parishes of Greek tradition will almost always have pews.
