If someone is very unsure about Torah, enough to be agnostic, yet accepts the possibility that Torah may be true and chooses to follow Orthodox halacha... then what would you say are some major challenges, and what are some answers to these?
For example, davening with honesty; ethical dilemmas regarding humaneness to humans or animals on Shabbat etc. (if unsure that the Torah approach is necessary).
How can such a person present honesty in some of the liturgical prayers? Is it by thinking of theirself as davening in the voice of the nation, rather than of theirself individually, or separately stating that these prayers are with the intention that they may be right? And what to do when ethical questions arise that aren't answered even by halachically acceptable leniency... if one isn't sure which value system to follow?
I guess that in this day and age, this is more likely to apply to animal suffering or shortening an animal's end of life suffering, if no gentile is present, on Shabbat or such. But there is also the question of spending money on halachic responsibilities rather than charity or other responsibilities.
