The seven sacraments are the life of the Catholic Church. Each sacrament is an outward sign of an inward grace. When we participate in them worthily, each provides us with graces—with the life of God in our soul. In worship, we give to God that which we owe Him; in the sacraments, He gives us the graces necessary to live a truly human life.



  • Must reside within the Parish Boundaries of Our Lady of Mercy Church.

Choosing the Godparents:

  • Godparents, if single must have all sacraments of initiation (Baptism/Confirmation/First Eucharist), and, if married, must be married through the Roman Catholic Church. They should actively participate in the Sacramental life of the Church.
  • All Godparents (married by the Catholic Church or single) must be practicing Catholics (attending Mass on Sunday).
  • Only one sponsor is needed but if there are two, they must be a male and a female.

At Time of Registration please provide:

  • Child’s original birth certificate from the city/state.
  • If baptism classes have been taken within the past 3 years, please present letter confirming classes taken at time of registration.


  • An interview with Fr. Jean Olivier M. Sambu, Pastor, will be on the first baptismal class.
