When people say that buying a second chapel means something has gone wrong, they don't mean that the act of buying the second chapel was the incorrect play. In fact, if your turn produces only $2 and you have to choose between chapel and nothing, chapel is quite often the right choice. The thing is, something must have gone wrong for that position to come up in the first place. Sometimes it's just bad luck, but often you made a poor choice earlier along.
Here it's pretty clear where you went wrong. You had no economy. When you get to open chapel + cultist, you have to do so, but you have to be aware that ntheater of those cards gains or produces coins, so you have to address this in your subsequent buys. Turn 3/4 you need silver. Then you can buy cultist turn 5 and shanty town turn 6 and you're on your way to your draw engine which can reliably draw and trash junk, and you can get better use of your 1st (and hopefully only) chapel.
