Remarriage is not adultery according to Christ if the previous marriage was ended because of adultery. As such these cases demand remarriage should be a possibility, not something permitted by the Catholic Church.
>more merciful
Hardly, it's clearly not optimal and the Orthodox Church knows that, but there do exist cases where it is permitted. To deny the ability to remarry under any circumstances goes against what Christ said.

>Peters power shared by the other apostles

AN apostolic chair. Not THE apostolic chair.
"You cannot deny that you see what we call heresies and schisms, that is, many cut off from the root of the Christian society, which by means of the Apostolic Sees, and the successions of bishops, is spread abroad in an indisputably world-wide diffusion"
Apostolic SEES, not See.
