What is spiritual friendship?
It is friendship that is rooted in Christ, for the purpose of growing in Christ.
The basis of spiritual friendship is a shared relationship with Jesus Christ.
The purpose of spiritual friendship is a common commitment to help one another grow in Christlikeness.
"Every friendship is formed around shared goods that identify the friendship and help the friends understand the life and purpose of the friendship. In spiritual friendship the principal good is a mutual love for Christ and a desire to grow together in Christ. This is what distinguishes spiritual friendship from other relationships. In spiritual friendships the friends are centred in Christ, they seek Christ, and they strive to live according to Christ. Through their friendship they want to help one another live a godly and holy life. They want each other to be resplendent in goodness." (Paul J. Wadell)
