incipiens a baptismate Joannis usque in diem qua assumptus est a nobis, testem resurrectionis ejus nobiscum fieri unum ex istis.
Beginning from the baptism of John, until the day wherein he was taken up from us, one of these must be made a witness with us of his resurrection.
Incipie ab baptismate de Ioanne usque in die quo assume es ab nos, teste de resurrectione de illo nobiscum fieri uno ex isto.
