From HERE:
John Wesley was an Anglican Priest, and hence his understanding of the Sacraments reflected, closely, what we today call "anglo-catholicism." For Wesley, a Sacrament was the outward sign of God's gift of inward Grace, to which Humans have the responsibility of outward response. Without our response, the Sacrament is not completed. This is, fundamentally, very similar (though not identical) to the Catholic understanding of the Sacraments. To this idea Wesley added the requirement that Jesus have clearly established the Sacrament in Scripture. Since this can only be said with certainty of Baptism and Holy Communion, Wesley -- following his Anglican tradition -- only recognized these two as formal "Sacraments," or as they are often referenced: "Sacraments properly-so-called."
