First Reading Philippians 2:1-4
1Therefore, if there is any consolation in Christ, any solace of charity, any fellowship of the Spirit, any feelings of commiseration:
2complete my joy by having the same understanding, holding to the same charity, being of one mind, with the same sentiment.
3Let nothing be done by contention, nor in vain glory. Instead, in humility, let each of you esteem others to be better than himself.
4Let each of you not consider anything to be your own, but rather to belong to others.
