One of the early considerations for a Shul is where will it be located? Will we rent or will we build? How will we pay for the pillars? These are not trivial issues, but they’ve been adequately addressed by many Shuls.
After the pillars, we need the people. A Rabbi to fill the primary role of spiritual leader. Some active-for-life members in some key roles. And the officers, board and committee members who keep the Shul running smoothing.
After the pillars and people are in place, we need to focus on the purpose of it all. The primary reason we’ve made all this effort – and that is to pray as a Tzibbur to Our Father in Heaven. Prayer is difficult, but it is an integral part of building a relationship with Hashem. It would be silly to spend so much effort in financing and running a Shul and not put a significant effort into improving our prayers.
Our Rav recently highlighted another aspect to consider. He taught that one of the primary determinants of spiritual success is the company we keep. Our friends have an extremely powerful influence on us. Our approach to prayer effects how others approach their prayers. It’s a self-referential loop which can bring us all to higher levels.
As we approach Rosh Hoshana it’s a great time to work harder on our kavanna during prayer so we can collectively advance in our spiritual mission.
Renting a space for a shul sounds like something that would, generally speaking, only be a temporary arrangement.
