A place to discover and discern your vocation as an Orthodox Christian. Christ calls each of us to be active members of his body, the Church. What does that look like for you?

Hear what SLI 2020 participants have to say about their experience!

“It opened my mind to a new way of thinking and to become a leader in life and in the church.”

“It was so incredible- the speakers, the content, the discussion and community were top notch!”

“I feel so fortunate to have been able to participate in SLI virtually. I was still able to meet people, really grow my leadership skills, and gain a deeper understanding of my faith. I hadn’t planned on participating in SLI this summer and I felt very fortunate to have been able to add it to my summer!”

“I learned so much […] I met so many people and became better friends with the people I did know. The break out groups and Sunday small groups were awesome!”


“I learned a good deal of valuable information and had the opportunity to meet and speak with wonderful people.”
