In 1981, in connection with continuing education courses at the East Asian Pastoral Institute (EAPI) in Manila, first contacts with Bishop Francisco Claver, SJ were initiated, who headed the newly established Diocese of Malaybalay on the island of Mindanao. Claver invited lay missionaries who started working in Malaybalay in 1986.

Fr. Martin Jäggi joined them with a team in 1992.

When Claver in 1995  became the Bishop of his home-diocese in the north of Luzon, he again requested a group of lay missionaries from Immensee.

Martin Jäggi worked there as pastor and retreat-master among the indigenous peoples of the mountain region  until 2013. His long-standing presence at various locations of the Philippines earned him the confidence of the local church as he was part of the new understanding of ‚Mission as intercultural fertilization‘ (Bp. Claver).

At the General Chapter of the SMB in 2013, Martin Jäggi was elected as Vicar General, which required his return to Switzerland. The Bethlehem Lay-missionaries (under the new name COMUNDO) continue their much appreciated work in the Philippino Church.
